Are you absolutely positive that your 3COM card is at the same IRQ as 
hard-coded on the card?  I'd get the 3c5x9cfg utility out, and double 
check.  I think the default kernel is set for ep0 at 10, but your card 
may be configured for 15 or something like that.  THe card will still 
function, but slowly.

Check that.  THen build a kernel that matches the card config, or 
configure the card to match the kernel, and go crazy.

If that doesn't work, come back.  All my boxes are using 3com cards, and 
they all work...
