Is it a lot of initialization code to get the chip into a framebuffer
mode, or is it that the chip can't be put into a framebuffer mode and
all text writing is quite complex?

If it's the former, then it's still C code that could be called from
SeaVGABIOS.  (Well, not quite, as the current SeaVGABIOS init runs in
16bit mode, but it wouldn't be hard to convert it to run in 32bit

Anyway, just something to think about.
