    Please don't top post.

    There was an attempt to resolve this issue a few months ago. The commit
    was rev. 1.10 of src/sys/boot/i386/Makefile.inc and the log message was,
    "Ensure GCC does not use FP registers in integer code." This fix was
    MFC'd to RELENG_5 a day later and is present in 5.4.

    For the life of me I can't remember if I tested the change when it was
    made. I think it didn't work for me, but I'll test it again tomorrow.
