okay, SINCE this this wonderful app turtns out to be a cluster fuck to install, I have worked out the quickj and easy way of getting it right the first time..
so., heres what you gotta do.

FIRST. you need to replace the mknod app with one from an older version of busybox.
I keep mine right here
http://me.256k.net/zaurus/fbvnc/mknod.tar.gz
_
without this, you will not get the keyboard simulator(kbddsim or something) installed, and wont be able to type through vnc. (gay)
_
untar that your SD card if you can.  someplace other than your rom space. since its BIG.
then;
ln -sf /mnt/card/bin/mknod /bin/mknod

this will replace the old one.
then install fbvncserver from the feed, to your SD card or whatever. 
once done,  you gotta do this, or else you wont be able to CLICK with your mouse on the screen,  because some IDIOT thought it would be smart to make the postinst require a friggin command line modifier to run.
LAME

do this.
/mnt/card/usr/lib/ipkg/info/fbvncserver.postinst configure
to get it running.

then. reboot. but make sure you dont do two reboots in a row or you have to reset the stupid thing, because of some ridiculously elusive "double reboot bug" that I beleive is still in full force.  

(allways suspend and resume after a reboot.)

once booted,  touch the top left most pixel of the screen,. and then the bottom right most pixel of the screen. then, open the konsole and;

ps -ef; should find  something like 
539 root        412 S   /usr/sbin/tssimd
running after the reboot, and touching the top left and bottom right corners.

also, you should find a file in /etc called tssim_cal.conf 

good luck.
