You should be able to do it from user space using Matthew Garrett's
vbetool[1]. If I understood it right, you can initialize the VGA
card with this, and then load vga16fb or vgacon.

If the card is VESA 2.0 compatible, you should also be able to use
it with uvesafb, which calls /sbin/v86d for x86 emulation.
