I was afraid it might take something like that - recompile without IDE or
IDECD. I'll have to think about if I'm brave enough to try that. Also
considering the libata PATA drivers are considered "experimental".

I did look at kernel-parameters.txt before posting to see if there was
something for libata like the old 2.4 option for having ide-scsi handle the 
CD instead of the regular IDE driver.  I didn't find anything there. I did
find this in ide.txt: "ide_core.noprobe=1.0". It causes the IDE driver to
ignore my CD drive (master device, secondary channel). But libata doesn't
pick it up automatically. If there is a way to get it to do so, I haven't
found it.
