Hello, Andreas.

Hey Jeff, all,
I was wondering why ATA_ENABLE_PATA and ATA_ENABLE_ATAPI are #undef'ed in
include/linux/libata.h by default, since reverting them to #define's was the
only way to make the ata-piix driver detect my CDROM on my new shiny ThinkPad
(Intel Corp. 82801FBM (ICH6M) SATA Controller). I would assume that most
people would want this. The drive worked out of the box on Ubuntu, so I
assume that their vendor patch includes this anyway.
Is there a specific reason that these are disabled? Are there any bad
consequences that I'm not aware of? Only reading the source really revealed
that this was the way to get my CD-ROM to work.
SATA ATAPI support still has some issues, but as you can read from the
following post, libata is almost there now.

I don't know much about PATA support. All I know is that ICH's seem
to generate a lot of noise in this mailing list w/ its legacy, combined,
ahci and whatever modes and no one setting seems to satisfy all. (If
anyone knows more about it, please fill in here.)
