I appreciate your enthusiasm, but I'd love it if I could use
both my 3c575 and Belkin BusPort Mobile Cardbus cards
simultaneously without them thrashing over IRQ11.  This is
still happening in test12-pre6 and seems to me to indicate
that all is not well somewhere in IRQ management land.

Just call me Scrooge.  :-)  On the other hand, maybe
I wasn't nice this year and am getting coal for
<insert holiday of preference here>.
