I've had no difficulty with 1950/2950 installs, as long as the disk
controller is the PERC 5/I.  I don't know if this holds for Vivek's
experience as well.

However, with the SAS5 controller (LSILogic SAS) AMD64 won't boot without

- ACPI / APIC disabled, killing SMP
- Any BCE interfaces disabled in BIOS
