I am running Qole's easy debian image on the galaxy tab. Work in progress on the mount - chroot - umount scripts; just taking bits of code from other people who did the same.
The vnc client I'm using to provide X is particularly good and has easy on-screen choice of mouse left/right keys, kbd, panning and zooming and is free for 1 remote connection: http://market.android.com/details?id...ocketcloudfree
Heartily adviced. I wish the open source client were so easy to operate.
