He did post his kernel and android patches online. Thats what I modified and used to get android working on the n900. Here are my patches against the kernel and android to get it booting. I also included folder from the android build details I used. Here is a quick and dirty.

You need to have bootmenu installed, and a file in your /etc/bootmenu.d/ called android.ext.item which contains

Code:
ITEM_NAME="Android (external SD, partition 3)"
ITEM_ID="android3"                        
ITEM_DEVICE="${EXT_CARD}p3"                                                  
ITEM_MODULES="mbcache jbd ext3 fat vfat"
ITEM_FSTYPE="ext3"                                             
ITEM_FSOPTIONS="noatime"
In the android-patches.tar.gz there are 2 files
n900_kernel.patch - you need to install maemo sdk and download the kernel source. After you patch the kernel, you can do a make ARCH=arm rx51_android_defconfig. You can compile using the scratchbox compiler (e.g. make ARCH=arm CROSS_COMPILE=/scratchbox/compilers/cs2007q3-glibc2.5-arm7/bin/arm-none-linux-gnueabi- -j4 zImage)

android_gralloc.patch - this allows android to boot past the android text console because of the "page flipping is not supported" issue. I couldn't find a patch to double the yres_virtual in the framebuffer driver, so this is a workaround which I believe is similiar to what bri3d did about the pmem stuff. Place this file in the root directory of your android source and patch it (e.g. patch -p1 <./android_gralloc.patch

In android-vendor.tar.gz there is one folder
bdogg64 - extract this folder to your android source/vendor directory. Feel free to rename it . After you do that, you should be able to build the android source (e.g. make TARGET_PRODUCT=n900)

You will also need a static build of busybox.

You will need a vfat partition on the first partition of your microsd card if you want android to mount it.

Copy your android build to the sd card, extract the busybox folder into the /system/bin/ directory.

After you copy everything to your partition on your microsd, you will need a couple of additional links.
1. /sbin/init which points to /init
2. /usr/sbin/chroot which links to /system/bin/busybox/sbin/chroot
3. /dev/console (e.g. mknod dev/console c 5 1)

These instructions are for the n900, so I suppose you are using the n8x0, you will skip the kernel patching and just build the source and modify the wifi section.

I will try to guide anyone through issues if I can. I will edit this post to clear up any confusion also
