Thanks Fabrice, that does everything I need now and the opaque data on
memory I/Os is very neat. I shall be ready to post a more complete
version of my pciproxy patch soon. Just one minor niggle regarding the
ROM code.

I notice you preserve the ROM enable bit, thats useful :)

However this still isn't solving my wierd problem with lspci on Linux
showing all devices as having a 2KB unassigned, disabled ROM chip where
normally it wouldnt print anything. In the config space the ROM bar is
0x00000000...

How are the BARs sized, by writing 0xffffffff over them then re-reading
once? It doesn't mention anything in the i440FX manual... Just waffles
on about the PMC extended register space.
