Well, on this machine GENERIC.MP will only ever work if you enable acpi(4).

> mainbus0: Intel MP Specification (Version 1.4)

This indicates that the machine claims to have the tables required by
the MP Specification, however, the fact that:

> cpu0 at mainbus0: apid 0 (boot processor)
> cpu0: Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz, 2333.39 MHz
> cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,P GE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE, SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,DS-CPL,VMX,EST,TM2,CX16,xTPR,NXE,LONG
> cpu0: 4MB 64b/line 16-way L2 cache
> cpu0: apic clock running at 333MHz

This is the only cpu that shows up, and:

> em0 at pci3 dev 0 function 0 "Intel PRO/1000MT (82573L)" rev 0x00pci_intr_map: bus 3 dev 0 func 0 pin 1; line 10
> pci_intr_map: no MP mapping found

all these "no MP mapping found" messages indicate that the tables do
not contain any useful information. The fact that the kernel
eventually panics is a good thing, since if it didn't your machine
would be pretty much useless running this kernel (no audo, network,
usb, only pciide would probably work).
