2.4.18 VIA MWQ patch (Athlon stomper) corrupts video wi

I have this problem, as well. The fix for me was simply not to perform the fixup at all. I'm not sure if clearing only bit 7 fixes the problem on my machine, but would grudgingly try it, if wanted. (I don't have particularly ready access to the machine.)
You should find 'Disabling VIA memory write queue: [xx] aa->bb' in your output. Values 'aa' and 'bb' are important - in other examples it modifies value from 0x3x to 0x1x. Unfortunately I could not find any hints whether we should clear bits 6,5 only on VIA_8363_0 if revision is < 0x80, or whether we should not touch them at all.
In all reports from last september I remember that clearing bit 7 alone fixed problems, but then patch which clears all three bits appeared from VIA without real world examples which were affected by it...
