please note that the MPU401 on ICH is very very experimental.
i tested nVidia nForce, which is ICH compatible, and on this chip at
least MIDI output works, but no input. on other cards even output
won't work likely..
unfortunately i cannot find any further info from the specification
documents. if someone finds/knows how to do it, please let me know.
