Nope, turning ACPI off doesn't make any difference except for assigning
a different IRQ:

:  atapci0: <nVidia nForce3 UDMA133 controller> port 0xffa0-0xffaf,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 8.0 on pci0
:  ata0: channel #0 on atapci0
:  ata1: channel #1 on atapci0
: -atapci1: <Promise PDC20378 SATA150 controller> port 0xd000-0xd07f,0xd400-0xd40f,0xd800-0xd83f mem 0xfc960000-0xfc97ffff,0xfc99f000-0xfc99ffff irq 5 at device 8.0 on pci1

:  ata4-master: FAILURE - ATA_IDENTIFY timed out
:  ata4-master: FAILURE - ATA_IDENTIFY timed out

Besides, I love my ACPI, and it's a clear regression -- if I revert this
commit, it all works again.
