FWIW, juggling the hardware so that the fxp and uhci controller aren't
on the same IRQ, and the printer works. However, the fxp is now
sharing IRQs with an an aic7890, and the uhci is sharing an irq with a
2940. Strange stuff.

And it looks like FreeBSD had nothing to do with it, other than not
working sharing the fxp & uhci controllers.
