kern/123140: SMP boot causes slow KB, ATA drives not detected

I've added some additional information to the bug report regarding ACPI
tables and boot without ACPI. If you happen to know where I can get
some technical documentation on the NVidia chipset and perhaps even the
board wiring (to see if the ACPI tables are just plain wrong) please let
me know. For now everything points to an improperly set up APIC, which
either doesn't respond to the interrupts from the hardware, or responds
incorrectly. I'm concerned about the timer because I read some comments
on-line regarding the NVidia APIC and the use of interrupt 2 for the
timer (and incorrect ACPI tables in THAT particular case, early 2007 as
I recall). If this is the case with my board (bad table) I can attempt
to work around it using the acpidump utility and the appropriate env
vars to load a 'fixed' ACPI table.
I hope this information is helpful in resolving this particular problem.
I'm having some difficulting using kgdb at the moment since it doesn't
seem to like my uplcom-based USB/Serial adaptor (it tends to crash/hang
the machine running kgdb as a client and gets 'out of sync' with the
serial data stream). When I can get this working I'll try to localize
the problem.
