It's much easier with the 2.6. sysfs interface -- one of the reasons I'm not really too excited about the cpufreq backport for 2.4.

Ok, after a very > quick look at the patch sources I don't see printk's there, too. Probably a BUG I introduced in the latest backport. Hopefully I'll have the time tomorrow to update it. In the meantime: what does /proc/cpufreq tell? Dominik
