power management in etch kernel ?

I've installed etch with default kernel on a laptop
with APM BIOS but no ACPI.  It runs a lot hotter
than it did with my customized kernel on sarge.
I added "apm=on" to the boot options to get apm -s
to work.
Still got heat and battery life issues that sarge didn't have.
Are there more boot options to enable the slower
clock and halt between interrupts kernel features?
Should I be using some other kernel?
