Thanks to all for the dumps, I've finally figured out what's going on and
also received a confirmation from people at ALI that I'm right, so here
is a patch which should make it work.

In almost all PC chipsets, the USB IRQ's are routed through the ISA bridge,
so it's the right place to search at :)
Have a nice fortnight
