[vortex] incorrect interrupt assignment?

I am seeing a problem with  3c900 and 3c905 cards in some recent
motherboards and am hoping someone can give me a clue as to what
is happening.

We're using a version of Oxygen, a Linux Router Project distribution.
We have a 2.2.18 kernel with the 15Sep00 version of the 3c59x.c
driver built as a module.  On older motherboards with 3c905 cards
everything works fine.

Repeatably on recent motherboards the driver seems to believe that
the card has been assigned an interrupt other than the one it
works with under Windows on the same machine.  Below is dmesg
output from a 733MHz machine with a 3c900 card.  In this case
when the machine is running Windows it has the card at interrupt 11.
The Linux driver believes it is at interrupt 10.  On several recent
Dell machines the card is at interrupt 11 but the Linux driver believes
it is at interrupt 3.  An example of this is below (2nd dmesg).

	David.
