Hi,

I'm not sure if you've already resolved the problem you were having.

You probably want to name the rom as "pci1002,791f.rom" instead of
"vgaroms/radeon.rom" - when the rom is named with the PCI id, the pci
id is passed into the rom at startup, and the rom may require this.

Also, how did you acquire the rom?
