I'm having problems with 2.4.2-pre3 and IRQ conflicts.  Last kernel that
I tried and worked without conflict was 2.4.0-test11.  Here are the
relevant messages that I get:

PCI bus 01 is an AGP bus, but there is no AGP video card present.  eth1
does function, but the sound card does not.  More information available
on request.
