well, it doesn't really matter since the kernel enables the IOMMU anyway. if you want to change the size you can pass that as a parameter on the command line.

The machine is working quite a bit better with pci=noacpi in leu of
disabling ACPI in the BIOS, but there are still those nasty errors in
reference to the ACPI tables being broken:
    ACPI-0362: *** Error: Looking up [\_SB_.PCI0.LNK0] in namespace,
AE_NOT_FOUND
search_node ffff8101428572c0 start_node ffff8101428572c0 return_node
0000000000000000

since it doesn't look like you'll get a bios fix for this you may want to look at building a custom dsdt. the kernel can load a custom dsdt from an initrd/initramfs. have a look at the acpi site (acpi.sf.net?). they talk about what's needed to do this. basically you can get your dsdt from /proc/acpi/dsdt and disassemble it using the iasl tools, fix it and then load it with an initrd. note that this is not really a trivial task :-(

And this one about the 8254 timer:
..MP-BIOS bug: 8254 timer not connected to IO-APIC

i've seen this before.. i think this may be related to the timer override not being done for your system (again strangely a bios bug...). why don't you try passing acpi_skip_timer_override on the command line.

And finally, I think that something else kind of wierd is happening with
the on-board sensors.  lm_sensors is having trouble detecting the fan
speeds and temperatures of the main board, but I will take that up with
their developers.

i think this may well be related to the ACPI issues you are having, since this is how the information is normally gathered.
