That is a very untypical last message and tells me quite
nothing about your problem. However, I have compiled an ISO
image for you, which features current binaries, uses GRUB's
vbeset, and works with QEMU. You can get it here:

   http://os.inf.tu-dresden.de/~nf2/tmp/vbeset-image.iso

You should try out this image using the following command
line options to see all debug messages:

   qemu -m 64 -serial stdio -cdrom vbeset-image.iso

If this works, compare your menu.lst file against the one on
the ISO image. You could also try to successively replace the
binaries on the ISO image with your binaries or vice versa.

Good luck!
