Hmm.  This brings up two questions for me.  First is, how do I tell if the
cpu is being run too fast?  Secondly, is this really a problem?  

I recall something about it being run at 2x  the first time I booted it; but
I don't recall which kernel that was.  My cpu is an AMD Athlon(tm) 64
Processor 3800+, with /proc/cpuinfo listing the cpu MHz at 2411.746.  the
board is identified by dmesg as an nvidia board, with an nforce3 chipset also
listed.  My kernel is 2.6.12-1.
