Does the BIOS have an option for ACPI 2.0 support?  We have several
Tyan Motherboards (S2882 - K8S, K8SD, K8SD-Pro) that give all kinds of
problems when ACPI 2.0 support is enabled.  Disabling ACPI 2.0
support, but leaving ACPI 1.x support enabled, lets the system boot
and run super-stable, in 32-bit and 64-bit modes, with and without
SMP.  No SCSI devices on these boards, though.  We're using 3Ware
Escalade SATA RAID controllers.
