The PATA specific code is almost entirely in the setup stages. Once the
setup is done then (with the exception of early PIIX devices, radisys,
triflex and a couple of other oddities) there is no "new" code actually
being run.

Well, I've just tried 2.6.16-rc2-ide2 on another VIA-based machine and it seems to work just fine, allowing me to say CONFIG_IDE=n :-) The CD drives work just fine including writing CDs, so I'm going to try writing a DVD soon, which should stress it a little more. However, I keep getting the following messages in dmesg:

[4294985.285000] Assertion failed! qc->n_elem > 0,drivers/scsi/libata- core.c,ata_fill_sg,line=2635 [4294985.377000] Assertion failed! qc->n_elem > 0,drivers/scsi/libata- core.c,ata_fill_sg,line=2635

This seems mostly harmless as everything seems to just work, but curious nonetheless.

HTH,
Chris
