Argh!  Unable to map interrupt, not I/O port.  Sorry.. An I/O port
mapping was the last thing that left me at a mountroot prompt on
this f'ing box.

The problem is really with mapping interrupts.  I've left mptable, and
verbose boot output from working and nonworking kernels at
http://people.freebsd.org/~gallatin/ata_irq/

As I said before, it doesn't seem to matter if I enable or disable
ACPI.  I've also tried set hw.apic.mixed_mode=0

A kernel from another box from June 19th seems to work, so
maybe it happened in the last 12 days or so.
