You're running into a couple of wrinkles about IRQs here.
1. The probes lie about the IRQ. It's what they want to have, not
what they find the board is set to. So probably the board really
is set to IRQ2.
2. IRQ 2 ceased to exist as an IRQ line when the PC/AT was introduced
back in 1984. Instead, IRQ 9 was used to handle the interrupt.
Sometimes it's still called IRQ 2, unfortunately, but our kernel
doesn't understand that.
Try setting the IRQ to 9 with the visual config.

Yes, look at the link0, link1 and link2 parameters. Unfortunately,
the man page doesn't specify which one to use for UTP, and I can't see
anything obvious in the source code. link2 is supposed to select
AUI. Try selecting various combinations.

It might mean that the driver doesn't understand the selection
mechanism. Which version are you using?
