 I have been working on such a driver.  The state is, it works fine
for something like workman (ie will merrily play your audio CDs,
though I haven't been bothered writing extraneous bits, eg the volume
control stuff[%], more proof of concept sort of thing) but I can't for
the life of me get it to read data CDs.  More to the point it hangs my
machine (controller timeouts etc etc) :-( I presumably have missed
something subtle to do with the way read() interacts with interrupt
driven IO.

 I had backshelved it, in the hope that inspiration would come my
way...

 I'm more than happy to give anyone a copy, at least it'd save you
retyping the ATAPI spec (~190 pages of FrameMaker or PS in
/fission.dt.wdc.com:/pub/standards/atapi/spec/SFF8020-r1.2).

Cheers,

	Ian

[%] though given how much my CD (NEC 260) varies from the spec,
whether it would work for mine at all...
