BeagleBoardUbuntu
Ubuntu 9.04 Alpha seems to be working quite well so here's a quick doc. Eventually this will probably be moved to ubuntu's wiki...
This page is about running a (ARM EABI) Ubuntu distribution at BeagleBoard. BeagleBoard will boot the (ARM EABI) Ubuntu distribution from SD card.

PC: Format SD Card
You will need a 1GB SD card or greater.
Standard System : ~xxxMB + Desktop environment (GNOME) : ~x.xGB
Starting with an empty SD card and using gparted, create:
50 MiB Primary Partition, fat32 Rest as ext2/ext3
PC: Setup SD uboot/uImage Partition
Mount your SD card fat32 partition. (/media/disk/)
cd /media/disk/ wget http://www.rcn-ee.com/deb/kernel/CC-v2.6.28-9a6536c-oer8 mv CC-v2.6.28-9a6536c-oer8 uImage (Set based on partition type, extX = ext2 or ext3) wget http://www.rcn-ee.com/deb/*****/ubuntu-extX.scr mv ubuntu-extX.scr boot.scr
PC: Setup SD ext2/ext3 Partition
Mount your SD ext2/ext3 partition. (/media/disk/)
sudo tar xfp armel-rootfs-[date].tgz -C /media/disk
Login & Install kernel-image
cd /home/<user> sudo apt-get install uboot-mkimage wget http://www.rcn-ee.com/deb/kernel/beagle/jaunty/v2.6.28-79d042a-oer10/linux-image-2.6.28-oer10_1.0jaunty_armel.deb sudo dpkg -i linux-image*
Extract linux-image's vmlinuz-*
dpkg -x linux-image* ./temp
Mount fat32 partition
sudo mount /dev/mmcblk0p1 /mnt
Build uboot compatible image and copy to fat32 boot partition
sudo mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux" -d ./temp/boot/vmlinuz-* /mnt/uImage
Clean up
rm -rfd temp
Sync, umount Partitions and Reboot
Advanced
Upgrade U-Boot
Using gparted, create a new 50MB Primary fat32 Partition on a blank SD card, or use your existing fat32 partition.
wget http://www.angstrom-distribution.org/demo/beagleboard/u-boot.bin cp u-boot.bin /media/disk

sudo mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "boot.scr" -d boot.cmd boot.scr
Mount SD card
For Kernel 2.6.28 with DSS2 setenv bootcmd 'mmcinit; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootdelay=2 rootfstype=ext3 ro omap-dss.def_disp=lcd omapfb.video_mode=1280x720MR-24@60' saveenv boot
Note: rootfstype=extX must match your format of the ext2/ext3 partition
