--- Comment #4 from Jung-uk Kim <jkim@FreeBSD.org> ---
You guys are not reading the code right.  x86bios_init_regs(&regs) before t=
he
commented line initializes all registers to zero.  In other words, I commen=
ted
out the line because it is unnecessary, i.e., STATE_SIZE is zero.  I am not
really sure what's going on but you can do "sysctl debug.x86bios.call=3D1" =
to
trace VESA function calls.
