AGP is just 66MHz 3.3V PCI with sideband addressing and pipelining.

That hadn't occurred to me. I know precious little about AGP.

Don't connect the SBAn or PIPE# pins, and it thinks it is a PCI card (i.e. FRAME# mode). No special logic here.

Neat... and so I guess PCI domain 1 provides a 66MHz bus for the AGP slot?

The p_pci-domain.diff patch in there should fix you up fine.

The SUSE installer looks updated with the patch, and the Fedora installer we were having trouble with needs it applied (I talked to the guy at RedHat responsible and he was still looking for multi-domain hardware to test, I don't know if he saw the patch yet).

Should be good! Hope this works for you. Thanks Peter Czanik for uploading it :D

Building an RPM with the additional patch from the 1.1.1-34 package now.

Looking at http://wiki.x.org/wiki/PciReworkProposal, I wonder if this reworking has happened yet. If it hasn't, then this patch may be superceded when the reworked PCI code appears.

Umm, okay, this is odd. I applied it and it didn't work. Still can't find the device.

The resulting packages are at http://choralone.org/fedora/ppc/. Beware that it'll think it's a downgrade from 1.1.1-34, so you'll need the -f flag when installing.

(SRPM is at http://choralone.org/fedora/SRPMS/xorg-x11-server-1.1.1-34a.fc6cust.src.rpm)

scanpci output:

Code:

In the output, so it doesn't look like it's domain-aware.

I'll fiddle more later. It's time for noodles.

FYI: it still does not work on SUSE. Here is the URL to the related bugzilla entry, please check there regularly if there is any improvement: https://bugzilla.novell.com/show_bug.cgi?id=202133

I installed Fedora Core 6 pre-relese (5.92) on my peg2 from dvd.
The X-11 gui would not start so I used text mode.
After the install the X server had the same problem (not being able to find the agp card).
I tried a 'yum update' after reading this thread and now X works.
Had to edit '/etc/inittab' to put the system in run-level 5 at boot.
Now fc6 boots with the graphic loader to the login screen.
