if you panic'ed with the CD module inserted, would you try to snooze withou=
t it?

or try this one:

/* wakebay.c - wakes a powerbook mediabay so the system doesnt crash on acc=
essing
 * a disk mounted before sleeping.  great for CD drives.
 *
 * Joseph Palani Garcia <jpgarcia@execpc.com>
 *
 * fairly simple.  IOCTL the mediabay to tell it the media changed.  (it on=
ly forgot
 * it in sleep.  we remind it.)
 *
 * 3 cases:
 *   nothing in drive      : does nothing, exits normally
 *   in drive, not mounted : acts, no effect (?)
 *   in drive, is mounted  : drive regains status, door locked, etc.
 *
 * this is useful for PMUD.  add it to the wakeup script to prevent crashes.
