Has anyone looked into cpufreq support for the AMD LX800?  It provides 
control over the CPU PLL via MSR 4C000014h, but it has this ominous 
statement in the datasheet:

       When using this register to change the PLL frequencies, the 
CHIP_RESET bit should be set.

 From viewing the other AMD cpufreq drivers, it appears they do not 
require a chip reset.  This sounds like a bad thing, since I don't have 
a clue how to save the cpu state, reset, and restore the cpu state.  Is 
this a big deal?

Thanks,

Paul
