Intel patch against X.org SiS driver version 0.9.1

The current SiS driver, as well as older versions, doesn't provide good support for SiS 662/671-based video adapters. I own an Intel D201GLY2 with SiS 662FX video adapter and, when starting X.org with this driver, multiple flickering vertical lines are shown on the screen. The only way to use X.org without them is either to reduce the resolution to 800x600 or the color depth to 8 bit.

Intel has released a modified driver that works good even at high resolutions (1680x1050) and with high color depths (24 bit).

The problem occurs on different platforms (I've tried x86 and x86_64), on different OS (I've tried various Linux distro and FreeBSD) and different driver versions (I've tried 0.9.1, 0.9.3 and 0.9.4).

I attach a patch for X.org driver version 0.9.1 made against the Intel driver, based on that exact version (so that only Intel changes are shown).

It is also being reported that the problem occurs on Intel D201GLY.

This is a patch against the former "premium" version (written by me, and not intel) and some changes which I don't recognize. If SiS had their hands on the code, handle with due care.

(I won't do anything with this as I quit development in 2005.)

OK, thank you. I think I'm going to diff it against your "premium" driver.
