Build 2.6.12 on FC4?

[Neal Becker <ndbecker2 gmail com>]

My wireless worked on FC3, but stopped working on FC4.  I want to try a
stock 2.6.12 kernel.  It doesn't compile the current FC4 gcc.  I grabbed
the patch linux-2.6.11-compile-fixes.patch, and it compiles.  But after
make, make modules; make modules_install; make install; it doesn't boot. 
Just says can't open console (/dev/console IIRC).

Any hints?

Oh, this is x86_64.
