Code:
apt-get install kernel-power-settings
I would put a note here:

  1. There will be a pop-up notification telling you that U-Boot will be "overwritten" (i.e. Kernel Power will flash it). Do not accept it.
  2. This will result to Kernel Power Boot Image for U-Boot to be not installed.
  3. Open FAM and check if Kernel Power Boot Image for U-Boot is not installed. If so, install it. You will not be prompted to flash/overwrite the U-Boot Kernel
restart n900

Code:
sudo gainroot
u-boot-update-bootmenu
restart with open ukeyboard
choose kp52

If you want to installing backupmenu:

Code:
apt-get install backupmenu
restart n900,with close ukeyboard,when shows the titles of u-boot,open ukeyboard and you see how loading bootmenu,choose maemo with..
I would edit this as:

  1. Turn off N900
  2. Keep keyboard open
  3. Turn on N900
  4. U-Boot will appear. You can select a Kernel.
  5. After selecting a Kernel, don't close the keyboard. Boot Menu (with Backupmenu inside of it) will initiate.

then advice from Pali:

Code:
root
ln -s /etc/bootmenu.d/20-Maemo5-kernel-power-2.6.28.10-power52.item /etc/default/bootmenu.item
after that the backmenu shoud properly load kp52
I think this is all,if somebody have other advice please share it
Just wanted to report that this works. I now have:

  1. Default kernel
  2. Kernel Power 52
  3. Backupmenu
...all powered by U-Boot. My next step now is to decide which CSSU I want to install, and then NITDroid. As for Nemo...I'll probably install it just so that I can write a Wiki Page/article about U-Boot and the steps to get it working with Backupmenu.

EDIT: I have modified the quoted message from "disappear" to show how I did it (basically it's the same steps but I rephrased them to be more descriptive/newbie-friendly).

I'll write an article for this in the Wiki Pages...not sure if this should be in a new Wiki article or if this should be placed/added in an existing Wiki Page/Article...please let me know your thoughts. I will likewise make a video of it (will reflash during the weekend to start all over).

Well, I put a config file for Nemo to /etc/bootmenu.d/

Code:
ITEM_NAME="Nemo"
ITEM_KERNEL="uImage"
ITEM_DEVICE="/dev/mmcblk0p6"
ITEM_FSTYPE="vfat"
ITEM_CMDLINE="root=/dev/mmcblk0p5"
But no entry is being displayed. What's more, I can't boot kernel-power now too (at first boot after installing kp there's was omap kernel and kp to choose, but now standard options (emmcboot, sdboot & etc.)). What am I doing wrong?

should u-boot-update-bootmenu be run as user or as root? Tried both, none work.

ITEM_DEVICE value should be in format:
ITEM_DEVICE="${INT_CARD}pX"
or
ITEM_DEVICE="${EXT_CARD}pX"

OK, my 21-Nemo.item looks like that:


Code:
ITEM_NAME="Nemo"
ITEM_KERNEL="uImage"
ITEM_DEVICE="${INT_CARD}p6"
ITEM_FSTYPE="vfat"
ITEM_CMDLINE="root=/dev/mmcblk0p5"
But still no custom entries (including kernel-power-bootimg) show up.

This looks like your first eMMC partition (MyDocs) is not valid fat, ext2 or ext4. Some Windows and Linux systems using some fat extension which is not supported by u-boot, so then u-boot cannot read bootmenu file from MyDocs.
You need to (re)format MyDocs partition from Maemo (to be sure that you use correct format) to one support filesystem (fat, ext2 or ext4).

I was using gparted to shrink the partition. But fsck-ing the partition gives no problem. Is gparted doing some strange stuff?

Problem is that u-boot support only subset of fat fs supported by linux and windows. gparted using dosfstools for fat support. And I think it enabled (or used) some fat extension which is not supported by u-boot.
