This seems slightly illogical: if Linux can't use VBE 1.2 to support a
linear framebuffer then how could a non-card-specific DOS program like
UNIVBE?

I hate to reveal secrets (I was going to put it in my VBE driver, but
it's just a guess so I don't know that it actually works), but I bet the
card supports a linear framebuffer and all you need is its address. If
you can get that (say, the user reads /proc/bus/pci, finds out where the
card's memory is and supplies it in an option to LILO) then you could
at least pretend that VBE 1.2 supports a linear frame buffer.
