Close, but not close enough.  The system would reboot a long time before
any drivers loaded.  (It was probably the kernel decompression routines
that were killing it.)  

I found the problem and am working to rectify it now---turns out that
with the new motherboard came a newshiny Pentium 4 processor.  That is,
not the same model that came with the old board, which was an Athlon,
and of course the previous admin had built a kernel specially for it.

Athlon kernels tend not to run very well on Pentium 4 processors!  Hence
the reboot.
