The IT department finally installed Max OS X Tiger on my G5 at work. I use a superb "macally ikey" keyboard. It works perfectly with tiger with one exception: the "smallerThan" and the ^ keys (and their shift variants) are exchanged which kinda sucks when you do HTML programming :). Everything works fine with the regular apple keyboard, though. Really weird. I tried the tool uControl but it only works with panther.
On a side note:
SSH via Smartphone via GPRS -> works really great!
