This seems to be one of the symptoms of buggy AGP support in the
system firmware.  Unfortunately, there is no longer any supported way
of installing FreeBSD without it -- AGP is in the GENERIC kernels, and
has been for quite some time now.
You might try booting to the loader and disabling AGP, but I'm not sure
that will help.

The kernel has to be inside whatever *BIOS* limit exists for booting.
