That has to be a good deal in general, but it leaves us AMD users swinging 
in a strong breeze. That microcode loading was in the kernel until sometime 
in the 2.6.20ish time frame, I can recall scanning dmesg's where it was 
loaded by about line 75 in past history.  Now its just an afterthought. :(

Thanks Kay.
