When using add-on Matrox G450 graphic card on Dell WS 220 and 530, agpgart is not probed. I need to force it using "modprobe agpgart agp_try_unsupported=1" command
We have force loaded agpgart on mga and r128 for a while now.
Bill, is this a agpgart driver issue with the WS220's chipset?
Probably, yes, if we need to add the 'agp_try_unsupported' parameter.
as a workaround, add: options agpgart agp_try_unsupported=1 to /etc/modules.conf
please add the output of "lspci; lspci -n" to this bugreport.

I need "lspci -vn" to get the subvendor id. This G450 card is not supported currently. *ANY* G450 card that shows up as G400, automatically is unsupported by XFree86, and requires at a minimum the output of "lspci -vn" to be submitted for the card to be detected properly in some future version of XFree86. This is a bad side effect of using subvendor id's on PCI cards.. nothing much can be done about it until the XFree86 team is made aware of new PCI ID's.

This is solely a kernel agpgart issue. Dunno why it's assigned to X.
Ok, the 0641 pci id is in kudzu already. It must have been added after RHL 7.1 was released... I looked into the XFree86 code and I do not see any sane way of working around this problem inside XFree86. If the above workaround works, please use it for the time being. As far as I am concerned, this is a hardware/kernel issue, not an XFree86 issue.
Whoops.. looks like we had a mid air collision there bill.. Reassigning to kernel..
