I compiled half a dozen kernels and now figured it out. This is the 
patch that causes rt2500pci to be slow. If I revert it, it is fast again:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d43c7b37ad787173d08683f05eadeea0398fefdf

I'd love to see this fixed before 2.6.25 is released, as it's a 
regression compared to -rc8.
