I've found that I can only get acceptable XBMC performance in Hardy by setting my frequency governor to 'performance' using cpufreq-utils (3GHZ Dual-core AM2), however I wasn't able to do this on my fully patched up Intrepid installation (same hardware) because the kernel isn't properly detecting my AMD AM2's Powernow features.
It's a long shot, but I wondered if it could be related to this thread (I'm suffering with the same problem. A patched SVN xbmc plays perfectly on Intrepid, but as others have noted is unstable, so not exactly high on the WAF.)
You can actually leave your CPU in ondemand mode, and lower the threshold to kick it up to full:
add the following lines to /etc/rc.local
echo 15 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold
echo 15 > /sys/devices/system/cpu/cpu1/cpufreq/ondemand/up_threshold
