Just about. I found that the de4x5.c driver will try with SHIRQ, and if
that fails, then try with SHIRQ|SA_INTERRUPT. Unfortunately, later in the
comments, it says this is an ugly hack, you shouldn't really use it, and
it might cause problems on a busy system. Well...the systems I want PCI
net cards in are our news server and a future squid server. Both qualify
as pretty busy.

Barring a BIOS upgrade, which AIR says isn't happening, is there any way
to force PCI devices to use different IRQs?
