As a side note, the cdrom drive in this powerbook G3 (Lombard) only really worked right, if at all, 50% (or less) of the time in 2.6 (it's fine in 2.4). It does seem to work now (maybe due to the pmac patches in -mm?) though. I'll continue to test the drive after more uptime and a few sleep/wakeup cycles.
