ep/X11 problems

[Stephen Montgomery-Smith]

I have a Dell Inspiron 7500 on which I have put FreeBSD Release 5.4.

The 3Com Megahertz 574B pccard ethernet card works well with the ep 
driver, except that after I run X11, it simply stops working.

I am guessing that it is an interupt conflict.  I have tried everything 
I can think of so that sp0 is not irq 11, most notably putting
hints.ep.0.irq="10"
in /boot/loader.conf, but it just doesn't work - the irq for ep0 is 
still 11.
