Ok. Misha confirmed that disabling 82365 works for him too.

I don't see what should have changed in 2.5.71 here, though. There are
some pcmcia changes there, but they all look like they are just changes
to the calling convention, not any _functional_ differences.

Anyway, I suspect that i82365 should just quit by default if a yenta
controller has already been found. I can't imagine that you'd have
both a yenta controller _and_ an i82365 controller, since there are
actually some port overlaps there (ie yenta should already register
the i82365 legacy ports).

Something is broken in resource handling that the i82365 driver
even tries to probe for the ports that are in use.

Russell, any ideas about why i82365 doesn't just leave the thing
well alone?
