Jeff, I've seen word of a similar failure on VIA 8235, but on those I've got neither the hardware nor the chipset documentation -- it would be great if I could get this to fail on hardware I actually have...
BTW. The latest stuff in http://linux-acpi.bkbits.net:8080/linux-acpi-2.4 should be able to boot with acpi=ht, or you can build with just CONFIG_ACPI_HT, and that will give you HT without any other parts of ACPI. Though if the platform has no MPS, this option leaves the platform in XT-PIC mode since it doesn't do IOAPIC discovery.
Feel free to dump the usual info into a kernel.org bug under component=ACPI and assign it to me.
Thanks, -Len
