    to fully initialize the USB subsystem using polling right from the
    get-go.  I dunno.

Isn't the BIOS on modern computers providing emulation of PS2 for USB keyboards? I have to organize a USB keyboard and try that out myself. If possible I'd like to have a clean solution. Right now, even delaying configuration until after interrupts are available seems to be a hack to me, at least doing it manually. Maybe something like NetBSD's autoconf framework would be a cleaner solution.
