For playing games, there are three options:

Existing fwcfg is the least amount of work and probably satisfactory
for isapc. fwcfg+dma is IMO going off a tangent. High memory flash
is the most hardware-like solution, pretty easy from a qemu point of
view but requires more work.
The only trouble I see is that high memory isn't always available. If
it's a 32-bit PC and you've exhausted RAM space, then you're only left
with the PCI hole and it's not clear to me if you can really pull out
100mb of space there as an option ROM without breaking something.
