For the problem of the fan, I advise you to try the non-free driver
fglrx in place of the radeon driver. It changes a lot on my R50.

ipw2100 does not support correctly suspend-to-disk but works perfectly
well with suspend-to-ram using apm.

for the speestepping, you do not need acpi, it works with apm. You just
need to load some modules (cpufreq, etc.)
