For legacy VGA memory? That's a good question. I've always assumed
that legacy VGA memory is handled directly in the chipset by redirecting
writes to the first VGA adapter it encounters (which usually happens to
be the builtin one these days).
I'm not sure it's possible to have a VGA device behind a bridge that
also handles legacy VGA memory because the bridge pretty clearly can
only have BARs within a certain region of memory (based on the bridge's
config space).
