Thanks, now that you mention it, I found some information that I was looking 
for, with a manpage browser, about the sound driver. :-)

Unfortunately, the ATA / ATAPI include files don't contain much information 
regarding the use of the ioctl()s. Should I use the CAM pass/xpt devices 
instead? I would like to access raw data on a CD drive (in particular, 
subchannel info from an audio CD).
