There should be an item in the Media menu that says "ASIO (via 
portaudio)" that should be checked in order to use the ASIO drivers.

For what it's worth, I've had the same problem in OSX routing MIDI 
through the IAC bus into various DAWs (haven't actually tried it yet on 
Windows XP). It's pretty frustrating. I get the feeling that the delay 
time set in the Audio Settings dialog is applied to the MIDI I/O as 
well, though that's just speculation on my part as I have never tried to 
verify that.
