There has been a longstanding problem with the Matrox G450 and perhaps other similar cards, with modes "above" 1280x1024-60 on ppc/ppc64 boxes running Linux. Higher resolutions and/or higher refresh rates resulted in a very noticably "jittery" display, and sometimes no display, depending on the physical monitor. This patch fixes that problem on the systems I have easy access to... I've tested with SLES9SP3 (2.6.5+ kernel) and 2.6.16-rc6 custom kernels on an IBM eServer p5 520 w/G450 (a.k.a GXT135P on IBM's ppc64 systems), and a colleague of mine (Ian Romanick) tested it successfully on an Apple ppc32 box (w/GXT135P). I also tested it on IA32 box I have with a GXT135P to verify that it didn't obviously break anything. In my testing, I covered single-card, single and dual-head setups using both HD15 and DVI-D signals, on both the IA32 and ppc64 boxes. While everything appeared fine on both boxes, I did encounter one problem: I can't get any signal on the DVI-D output on the ppc64 box. However, this is also the case without my patch. I just noticed that screen-blanking only occurs on the primary display as well. Signed-off-by: Paul A.
