(In reply to Max Staudt from comment #18) > Please note that this may well be a separate bug from the Matrox case. I search fruitlessly on bugs.freedesktop.org and bugzilla.kernel.org for anything similar to comment 13 et seq.... (In reply to Felix Miata from comment #22) > I have no Radeon AGP newer than rv250.

I replaced the rv250 gfxcard in host a-865 with an rv200 (Radeon 7500). It solved all problems described in comment 13 et seq., suffering AFAICT only https://bugs.freedesktop.org/show_bug.cgi?id=90572 I tried the rv250 in host gx270, but it won't POST with it. Host a-865 is logistically unsuited to try replicating with another OS, so I'm trying to find some other x86 AGP host in which to try the rv250 that has a CPU with at least sse2 to see if this trouble can be replicated in Mageia, Fedora or other before filing a new bug....
