Hmmm.  When I search their archive I get only one message that says that
a P6DLF with a 2940u2w is not detected at boot.  The same message says
that a P6DLS is probed and detected just fine with the defaults, which
is also my experience with all the 2.0.3X kernels and all the recent
(>4.0) aic7xxx drivers.  The kernel I'm writing this message under is
2.0.33 with 5.0.7/3.2.2 installed and the onboard 2940UW (as far as I
can tell) works perfectly.  I also searched on generic 2940UW and
aic7xxx plus "scanning" hangs, but got nothing like the message I'm

Your idea of trying to build and boot a non-SMP kernel is sensible and
I'll give it a try.  At the very least, I might isolate the problem as
being in the SMP vs. the non-SMP code, and it would be cool to get even
a non-SMP 2.1.X kernel to boot...
