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:
 processor	: 0

 temperature 	: 0-3 C (uncalibrated)
 clock		: 400MHz
 revision	: 2.3 (pvr 7000 0203)
 bogomips	: 793.71
 machine		: PowerBook4,3
 motherboard	: PowerBook4,3 MacRISC2 MacRISC Power Macintosh

 pmac flags	: 0000001b
 L2 cache	: 512K unified

Note that the maximum CPU speed is 900 MHz.
