I actually had the drive out this last weekend, and you are correct,
the drive has a standard PATA interface, and the replacement drive I
put in also has a PATA interface.  The replacement drive, the 60GB
Toshiba from my old notebook, worked fine.

However, the kernel is definately using the SATA driver from libata to
access the hard disk.  When using the IDE driver I don't get DMA on
the hard disk or DVD drive.  Using the development libata stuff from
http://www.kernel.org/pub/linux/kernel/people/jgarzik/libata/ I get
DMA on the hard disk (I get that with the in-kernel driver, too) and
DMA using ATA passthrough to the DVD writer (this currently requires
the development patches).
