Interesting
All right: I may be able to offer some tips:
I have the mouse, and keyboard. First of all, the devices will not work properly unless you are using built-in Blue Tooth or the D-Link DBT 120.
That being said, my 17" iMac with DBT-120, and PB G4 were also not awakening from sleep with wireless devices. I found out what was up: With the CD that came with the mouse/keyboard, first install the software, THEN run the firmware updater: this was at least the case with 10.2.8. Perhaps in Panther it has changed. Anyway, good luck.
