maybe vaxen is used to have +2000 fps like glx-gears is giving

by the way, karosh your installer ended a two week lasting nightmare of CVS build after build - many many thanks!
and vaxen: why don\'t you want to use 100% of your cpu?
if you really want to save some cpu-cycles, you can use a userspace program to set the cpu frequency down. there are plenty for windowmaker (can not think of the name right now, wmcpuload or something like that its called). but, you need to enable the performance governors for that in the kernel.
