 Great.  I get to rewrite my initscript for the ondemand governor to 
test for yet another kernel version, and write a 0 to yet another sysfs 
file, just so that any compile I start in an xterm on my desktop box can 
make the processor work for its living.

 Just what have you cpufreq guys got against nice'd processes ?  It's
