I applied this patch for a kernel build on another PIIX based machine around here, plus the 'ata_piix.c' patch that was tested earlier, and the patched kernel booted without problems. I'm guessing that between the time the patch was initially posted and now other people have tried it out, but I can confirm the patches did not cause problems on the machine (SMP PIII box). A little more testing info for those wanting some results. The kernel, btw, was Linus' git tree from this morning.
