Hmmmm....  I get that message when multibooting regular FreeBSD
(3.1-stable kernel, but 3.1-release bootblocks) and NT,
using the NT boot loader to load our /boot/loader sequence.
Works fine when /boot.config contains

1:da(0,a)/kernel

so there is nothing wrong with the kernel.  I suspect a mismatch
somewhere between the 3.1-release boot stuff (specifically,
/boot/loader) and the 3.1-stable kernel, but I haven't gotten
around to a make world and installation of new bootblocks.  You
might try cvsupping the 3.1-stable boot hierarchy, and using the
new boot blocks on the floppy.  (Although I don't know what that
would do to your regular system disk.)  A full make world might
work better.  There are hints of this kind of problem in the
stable mailing list archives, I think.
