Unknown.. it's different on every card.  THey have a standard VGA interface
for text mode, but they all tend to have a "stop behaving like a VGA card
and go native" switch for running in non-banked modes.  This is different for
every card.. which is why syscons can't do it as-is.  Syscons would also have
to stop things like any in-flight busmastering DMA etc..

The only way to do this is to move the hardware-specific parts of XFree into
the kernel and provide a ddx device for XFree to use.

Cheers,
