Comment(by fhn):

 Some more news:
 I found the changeset for rev 593 and undid some changes.
 I traced this bug down to "pVia->UseLegacyModeSwitch = FALSE;" in
 via_driver.c, line 919 in rev 701.
 Whenever i comment out this line, so that UseLegacyModeSwitch falls back
 to it's default value of TRUE everything seems to work fine, no more green
 bars.

 Since I'm an absolut newbie to graphic drivers i have absolutely no clue
 what this LegacyModeSwitch could be. Maybe someone could give me a hint?

 While playing around with UseLegacyModeSwitch set to false and disabling
 some lines of code where it got used inside via_driver.c i found, that
 ViaCRTCInit(pScrn); in line 2701 (again rev 701) has major impact on my
 green bars. Setting the preceding if clause to true or false leads to
 funny green, blue or red bars.

 I'm in the dark.
