Should be called from the IDE notify chain perhaps. See the last function
in ide-pmac().
Yep, this should be done juste before the pmac_ide_dma_onoff() call in
ide-pmac.c/idepmac_notify_sleep(). It should be done regardless of the
disk beeing in a bay or not since new machines will ultimately support
sleep on desktop boxes too. Something like

switch(drive->media) {
  case ide_disk:
    // spin up the disk
Aye. Can you be more specific about 'do whatever needs to be done'? Can I
just send the disk a read command to wake it up? Send a reset
command?? Will a reset command hurt if I always send a drive reset
there?
I'll try that on my Lombard to see if I can save the nasty timeout when
the drive was powered off with hdparm -Y ?? That would help fake sleep
mode on the Pismo, or did you implement pmu sleep/wakeup there yet?
