Latest MFCs break boot on amd64 notebook.

[Andrew Lankford]

The latest MFCs (the eagerly awaited boot-time module
 loading functionality on amd64) compiled ok, but my
machine freezes and then powers down shortly after
"boot" from the loader.  I would try to give you all
more details, but my old working kernel seems to be
lost, and so I'm pretty much down for the count.

Any other amd64 users out there tried rebuilding
their kernels in the past few hours?
