Try booting -v and see how much farther it gets.  On my -current box,
right after that is the pcibios/PIR probe, then the ACPI tree walk to
attach devices.  Its possible the ACPI code in your system is fatally
flawed.

Have you tried upgrading the BIOS?

Interesting the BIOS wouldn't manage it in non-ACPI mode.
