In 2.6, sparc64 now has pcidomains. This breaks x.org, but thankfully, the fine folks over at Gentoo SPARC have a patch to fix the issue, without breaking compatibility with 2.4. Please apply the attached patch, and submit it upstream, since I'm not entirely sure about how to do this.
Created attachment 99280 [details] Patch to fix pcidomains for sparc64
I'll take this one since I've been doing a fair amount of other PCI work and have delt with the domain issue previously.
rolled patch into existing xorg-use-linux-pci-only.patch because they are closely related, that patch still needs to be turned on in the spec file once the branch issue for FC2 is resolved.
If you guys want to send this upstream, please do. I've been swamped lately and haven't had spare time for anything.
