I also have the same issue and have not been able to boot any kernels 
from recent builds. I know that  r194437 works for me

I am also using ZFS on an intel Core2Quad

If I boot a recent kernel I get (copied on to paper and type retyped here)

Every time I try a kernel it always bombs out with cpuid 3 but the hwpmc 
line can be anywhere between "hwpmc: TSC/1" and "hwpmc: 
TSC/1/64/0x20<REA> IAP/2/40/0x"

I cant even start in to single user mode (get the same error as above.)

If I try to boot with ACPI disabled I get

the loader prompt:

and then remove the invalid options from /etc/fstab
