    This is still in the boot loader, and Dragonfly is using FreeBSD-5's 
    boot loader so it is not unexpected that it would fail in the same
    way that the other FreeBSD's fail.  That it also fails in FreeBSD-4
    seems to indicate that the problem has been around for a while.

    We are not going to be able to fix this for the release, but it is
    becoming increasingly clear that I am going to have to rip open the
    boot loader at some point and implement the missing emulations.
    I sometimes have 'odd' BTX failures on my AMD64 boxes as well, so
    you are not alone.  I *KNOW* that bootloader is doing something wrong
    somewhere, I just don't know where.
