Panic booting vmware i386 after SRAT update

[mdf at FreeBSD.org]

I have a 2 cpu virtual image of FreeBSD current.  It panics during
boot after building in the NUMA support.

I'll transcribe the SRAT bootverbose messages and panic message as best I can.

Table 'SRAT' at 0xfef07f6
SRAT: Found table at 0xfef07f6
SRAT: Found memory domain 0 addr 0 len a0000: enabled
SRAT: Found memory domain 0 addr 100000 len ff00000: enabled

then some MADT: messages about finding cpu 0 and 1

 cpu0 (BSP): APIC ID:  0
 cpu1 (AP): APIC ID:  1
panic: SRAT: CPU with APIC ID 0 is not known

I'm playing around now with trying to figure out what went missing,
but I thought I'd send this out now.

Thanks,
matthew
