Look at /proc/acpi/processor/CPU/power. Does the bus master activity drop  
to 000...000 if you do nothing ? Do the cores reach C4 or deeper ?

For all i know even 2.6.17 cannot do these two things (unless you unload  
USB and wireless). Windows can (there is a patch released 4-6 months after  
CoreDuo was launched). I think of that as a problem.

There was also the problem with switching off unneeded PCIe lanes if the  
gfx is idle. Does the most recent fglrx do that ? (i didnīt check the last  
release yet,... anyone ?)
