maybe not what you want to hear, but apm works great on my r40
(pentium-m, ati 7500), acpi was always iffy.  ACPI support for linux
was primarly implemented so that non-legacy machines would function
properly.  Once that was accomplished, development tailed off greatly,
so there's still much work to be done for full acpi support.  Of
course, the acpi spec is insanely huge and complex (thx, intel).

thinkpads generally come with excellent apm support.  Mine suspends to
ram and disk, cpu throttles, video throttles, fan throttles, all
yeilding great battery life.  It just works.  If you were running a
laptop from a different manufacturer, you'd probably be stuck having
to use acpi, but not so with thinkpads.

just an idea,
