What video card is this ?
It's possible that your config ops for the AGP don't work properly. Make
sure you are really generating type 0 config cycles.
Also, this "cannot allocate resource region" smells bad. Can
you check what the BARs of the host bridge are supposed to mean ?
I hope it's not yet another brain dead bridge that puts the system memory
in a BAR... in which case we'll have to "hide" it from linux PCI subsystem.
Ben.
