pcnet32 is used on the Netwinder, which we still have supported in the ARM
tree.  Even worse, the Netwinder has the Cyberpro capture IRQ missing a
resistor, so it defaults to "asserted" and can trigger a stuck-IRQ, so
it's best not to allow probing of that known bad IRQ.

SA11x0 stuff uses smc91x.c

Some EBSA285 systems use that, Compaq Personal Server (which is my wireless
AP using hostap) does.

ucb1x00.c definitely uses IRQ probing on SA11x0 platforms.
