I have sucessfully gotten pdaXrom to work on my 6k
This is how I did it:
Flashed to Guylhem's ROM (to partition the internal memory as one moint point)
then flash to RC10 of pdaXrom for the 6k
login as "root"
Then type "/etc/rc.d/init.d/wlan start" then "dhcpcd -G 'your gateway IP' wlan0"
That should connect you to the internet (assuming you dont have a WEP key)
Do a "echo 'src pda6k http://18.104.22.168/rc10/Zaurus-SL6000/feed/' >> /etc/ipkg.conf"
then the ususal "ipkg update", "ipkg upgrade"
now type "startx"
matchbox should come up within a few seconds (be patient)
the system should be functional now
As for extra packages(like KDE, firefox, etc...) install them to your CF card
DO NOT INSTALL TO THE SD CARD (there is a driver bug)
I am currently working on a X11 configuration app for the 6k specific hardware
I will release it shortly...
