O.k. got that nice QuickSilver G4 with 2x1.8GHz (Sonnet) and an aluminium (full size) Apple kbd. It does work, but on every powerone the OF will open the cd-tray before booting. I also witnessed this behaviour with the 2x2.3G5 and a NoName (actually Genius I think) kbd. On the QS I tried 3 different KBDs (as in 2 Apple-aluminium and 1 Apple white/acryl) both on the internal USB1.1 and on a PCI-USB2 card, all the same effect. But I do know that the last time it did work with one of the aluminium-KBDs, so I guessing at some OF-variable being borked (system has been without power for a month).
