output of `cat /proc/cpuinfo`

Hardware: Intel Q6600 2.4Ghz (clocked at 2.8Ghz)
Software: Gentoo Linux ~amd64, running Linus's HEAD.

Problem description:
The first core appears to be locked at a slower speed. The CPU has two
potential speeds: the maximum speed and and the maximum speed divided by 1.5.
CPU2, 3, and 4 all operate correctly at 2.8Ghz, while CPU0 remains stuck at
1.87Ghz. The problem is observed at stock speeds. I don't remember when it
first appeared, but I believe it was 2.6.34.
