thanks for the diff

i made the (first) change; setting to 1, and dmesg gives:

--snip--

so theres no error, but my inclination is that its still not enabling the
2nd cpu.  again, i'm not sure how to verify for SURE whether it is or
not.. i've just been running top and looking for 2 cpu's running

is there something in dmesg i should be looking for in particular?

i'm going to try now by setting physical_cpu to 2..11 as you indicated and
see what happens

thanks
nathan
