Except that it didn't work.

With acpi=ht, the boot sequence proceeds past the pciehp module, but
hangs up later, not always at the same place.  With acpi=off, it
consistently hangs during (of all things) starting cups.

However, leaving acpi alone and changing the timeout in grub.conf from
5 to 10 seconds (which I did for another reason -- the monitor wasn't
coming on until the 5 seconds was already past) seems to have cleared
it up.
