Keypebble is IMHO too slow and rather broken...

By the way, I've hacked the xf4vnc server and fbvnc client to use a
shared memory region for the pixmap, this completely avoids the need to
push pixels through the TCP socket, and makes it as fast as a local
(unaccelerated) X server.  I have zero time to work on it, but I can post
the patches here if anyone is interested.

chroot was just easier to set up - you have to be a bit careful with
handling the sdmmc module needed to talk to then new root drive.

I am running a pivot_root setup on my C750, the files I used are in
http://pocketworkstation.org/files/c700-kernel/romupdate-native-debian-2003-03-20.zip

The init script (called instead of /sbin/init from the kernel) is
appended. It took me some head scratching to figure out how to do a read
with timeout in plain /bin/sh :-)

Wireless configuration is a bit of a mess, with the incompatible wlan and
wlanng drivers and tools. I don't understand it myself so I can't help
you there :-(
