	PowerComputing PowerWave 604e/180, 64MB DRAM
System: NetBSD macppc 1.5.2 NetBSD 1.5.2 (POWERMAC) #0: Thu Oct 11 18:06:14 PDT 2001 root@macppc:/usr/src/sys/arch/macppc/compile/POWERMAC macppc


>Description:
	Power-save mode is never enabled for machines with the 604ev processor,
	even though it seems to work and lowers the temperature of the air
	leaving the machine noticable.

	A diff is provided below for enablement of it.
>How-To-Repeat:
	Use thermometer to measure temperature of air leaving box with idle
	machine. Patch, build, reboot, repeat measurements.
>Fix:
	Diff below.
