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):
Back to C!
zapping low mappings.
