I've been having various trouble with my iBook lately, including random
freezes, not waking up after going to sleep sometimes, and sometimes not
going to sleep. Since applying the patch you posted, everything seems
fine, though I may be speaking too soon.

My /proc/cpuinfo for reference:

Note that the maximum CPU speed is 900 MHz.
