There have been problems in the past with older versions of x86emu not
properly emulating some x86 instructions.  However, to be sure if this
is the problem, we'd need to see the output from the debug log.  See:
  http://www.seabios.org/Debugging
to enable debugging, and please post the full debug log.

FreeBSD VESA console not working with SeaBIOS

[Jon Doe]

Here's a log showing a boot into X, then switching to console, then
trying to kldload vesa.ko. Looks like X is happily probing vbe modes,
but the console chokes with "SeaVGABIOS: x86emu leal trap!".
