There's a new driver for the old Panasonic (Matsushita) CR-56x
CDROM drive. It's smaller than sbpcd, can detect disk changes,
works with Workman, etc. Note that there's no SoundBlaster
interface support in the driver yet.

Also a question to device driver gurus:

Is there a reliable delay-with-sleep method for polling
drivers? I experienced strange early rescheduling with
the popular current->state=INTERRUPTIBLE; schedule() method.
And, the timers allow delay at least two jiffies.
