Yeah.

OK.  BTW: while building I got a compile error:

arch/i386/kernel/cpu/cpufreq/speedstep-smi.c: In function `speedstep_set_state':arch/i386/kernel/cpu/cpufreq/speedstep-smi.c:183: error: `freqs' undeclared (first use in this function)

I worked around that to get it to build, but something needs fixing
there, obviously.

The messages I get before the oops (and the oops for posterity):
