Have you tried building your kernel with an absolute minimum configuration?

ARe you trying to boot from the same disk drive that was attached
to your 1542, and is the extended translation setting the same
in the 2940 as it was in the 1542 (does the 1542 have extended
translation?)?

Boot with verbose (aic7xxx=verbose) and verify the driver is
correctly detecting the cables.  Unless your plugging and
unplugging an external device on your system, I don't see
the advantage of auto-termination anyways.  Of course, I
also hate plug-n-pray and would rather have jumpers ;-)  It
sucks having to keep DOS around just to configure these
kind of devices.
