I'm sorry - I forgot that the way I manipulated the IRQ used by ep0 was
to change pccard.conf. I removed "5" from it. Userconfig has no part in
this. So, unless you can edit pccard.conf, you're out of luck.

If you have another pccard, perhaps you could try inserting it and
making the machine use IRQ 5 for that pccard, and the next available IRQ
for ep0. But I doubt that'll work.

That's the consequence of an IRQ conflict.
