Maybe ubuntu could be the solution to flashing usb-less N900's. I haven't tried it but maybe it would work if we copied the maemo binary flasher from rootfs and used it booting from ubuntu. Fortunately my usb's are still in place but I thought maybe putting this idea on record here might help a poor fellow who's usb is out.

Doesn't look good.
I managed to get some of those errors straightened out, but I'm stuck here:
error: implicit declaration of function ‘console_lock’ [-Werror=implicit-function-declaration]
As I understand what I read here: http://irclogs.ubuntu.com/2011/06/01...untu-devel.txt , it's not going to fly on 2.6.37, as console_lock isn't in the kernel until 2.6.38.
Bummer.
Perhaps an older version?

I grabbed all the 3.01.00.07 packages from here.
http://ports.ubuntu.com/pool/multive...les-sgx-omap3/
When I tried dkms, i got
error: implicit declaration of function ‘omap_rev_le’ [-Werror=implicit-function-declaration]
According to https://wiki.ubuntu.com/ARM/n900 this patch: https://wiki.ubuntu.com/ARM/n900?act...revision.patch might do the trick.
Alas, I need to go to bed. I will be busy for the next few days and will not likely have time to get back to this for a little while.

So we will never have hardware acceleration in ubuntu 12.04 because the powervr libs are armel?
EDIT: What about the meego TI SGX driver? ti-omap3-sgx-bin-1.4.20090218.189-armv7hl.tar.gz

ITEM_USEATAG=1 is used instead of ITEM_REUSEATAG=1, the system won't boot using the later.(this happens even when booting maemo with kp if ITEM_REUSEATAG=1 is used in KP item file)

Quick update.
I placed the meego rescue zImage and initrd into /boot and created a bootmenu.item for it in /etc/bootmenu.d/ (I can post this if anyones interested)
This allows me to repartition the whole eMMC over USB without having to install backupmenu (nasty).
So I shrunk the fat32 mydocs partition, moved everything else to the left and created a fouth logical parittion with two extended partitions, one for Ubuntu 12.04 ext4 (mmcblk0p5) and one for NITDroid ext4 (mmnblk0p6).
Then I got the Kubuntu 12.04 omap armhf image and mounted it and copied all files to my Ubuntu eMMC partition (mmcblk0p5).
Also placed unknown.obvious' uImage in the root and applied most fixed from the install.sh and installed the kernel and kubuntu-mobile-integrations debs using chroot.
From the maemo root I copied everything in /lib/firmware/* to my Ubuntu /lib/firmware
Here's my Ubuntu.item:
Ubuntu fstab:
It works but I'm having some problems.
- Wireless doesn't work
I double checked the firmware files (copied from maemo) are in /lib/firmware but no connections show up
- The n900 keymap gets loaded but I cannot type numbers using the blue shift button
- It's a bit slow
No video hardware acceleration :P
I can post detailed instructions for installing kubuntu but I think it's best the installer.sh gets updated for this.
So far no crashes

A quick update.
I replaced Kubuntu 12.04 with the regular Ubuntu 12.04 (omap armhf).
Still using unknown's 2.6.37-n900 kernel, kubuntu integration deb and the fixes/workarounds from the install.sh script.
Only this time I used the firmware files from the Meego CE image.
- Wireless works like it should
- Keyboard is OK now (I can type numbers)
- Stable, not a single crash for over two hours
However it's still VERY slow.
It boots up fast but after login to Unity it will become a nightmare:P
Firefox takes op like 2 minutes to open, and 3 minutes before I can type in a URL
"top" shows me that Xorg, gnome stuff and Unity are taking up all of my memory and cpu usage.
I already tried setting elevator=noop and using ext4 for rootfs with noatime but no luck in getting it faster.
I'm going to install the Meego CE image onto my NITDroid partition and rip out the sgx drivers/xorg config to see if I can get EGL working in Ubuntu.
