The instruction of setting up debian in G1 is in saurik's site here http://www.saurik.com/id/10
But some of the information are outdated, as the rooting is very simple now and the busybox comes with one click z4root
z4root is here http://www.multiupload.com/EPKDWWLWD9
I like this method as the Debian system is installed in a standalone img file which can be copied to other Android phones.
(1) Download the Debain G1 image here
http://rapidshare.com/files/161776007/debian-armel-750.img.bz2
or here

There is a ubuntu.img out there and is 2G in size (but trust me, running a graphical desktop via vnc is overkilling on mobile device). If you want shell access only, this debian.img is better.
(2) copy it to sdcard.
adb push debian-armel-750.img.bz2 /sdcard/(3) su shell access to Tab
adb shell
su
(4) unzip the file in Tab. The image after unzip is 750M in size, so make sure you have enough space in sdcard.
cd /sdcard
busybox bunzip2 debian-armel-750.img.bz2
mv debian-armel-750.img debian.img
(5) setup mount and chroot
create and run this script in
cd /data/local
busybox vi startdeb.sh
- startdeb.sh Select all
export kit=/sdcard
export mnt=/data/local/mnt
export TERM=linux
export HOME=/root
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH
busybox clear
busybox mkdir -p $mnt
busybox mount -o loop,noatime $kit/debian.img $mnt
busybox mount -t devpts devpts $mnt/dev/pts
busybox mount -t proc proc $mnt/proc
busybox mount -t sysfs sysfs $mnt/sys
busybox mkdir -p $mnt/mnt
busybox mkdir -p $mnt/mnt/sdcard $mnt/mnt/system
busybox mkdir -p $mnt/mnt/data $mnt/mnt/dev
busybox mount -o bind /sdcard $mnt/mnt/sdcard
busybox mount -o bind /system $mnt/mnt/system
busybox mount -o bind /data $mnt/mnt/data
busybox mount -o bind /dev $mnt/mnt/dev
busybox mount -t tmpfs tmpfs $mnt/tmp -o noatime,mode=1777
busybox chroot $mnt /bin/bash
#After exit command is executed clear it all up
echo " "
echo "Shutting down Debian........"
umount $mnt/dev/pts
umount $mnt/proc
umount $mnt/sys
umount $mnt/mnt/sdcard
umount $mnt/mnt/system
umount $mnt/mnt/data
umount $mnt/mnt/dev
umount $mnt/tmp
umount $mnt
run the startdeb.sh script
sh startdeb.sh
# now Tab should be in Debian System
(6) do some fixing and change root password and install OpenSSH and start it
rm -f /etc/mtab
ln -s /proc/mounts /etc/mtab
passwd root
apt-get update
apt-get install debian-keyring debian-archive-keyring
apt-get update
apt-get upgrade
apt-get install openssh-server openssh-client
/etc/init.d/ssh start
(7) If the default package source does not work, you can change this file /etc/apt/sources.list to
deb http://ftp.us.debian.org/debian lenny main
(8) Then you can ssh to your Tab by using ssh root@xxx.xxx.xxx.xxx after enable wifi in Tab, where xxx.xxx.xxx.xxx is the IP address of Tab.
(9) If you want to change the DNS server say to Google Public DNS
echo "nameserver 8.8.8.8" > /etc/resolv.conf
echo "nameserver 8.8.4.4" >> /etc/resolv.conf
