The commenter on http://www.openchrome.org/trac/ticket/145 ,
<rikz at yandex.ru>, has been mailing me privately, saying that he
hasn't found a working kernel, going as far back as 2.6.19, and
that he would soon try downgrading to xorg 1.3. I've urged him to
post his findings to the openchrome-user mailing list, but he
continues to think that negative findings are no findings at all.

The disabling does not do any harm, and it does appear to prevent
screen corruption and lockups on the affected chipsets. Both of
those are _very_ annoying events, and should be prevented at all
costs. There are few things more frustrating than rebooting after
a system update and getting only a black screen or seeing the
desktop slowly fall apart under your eyes. When I first started to
use the via driver, it took me a whole month to find out that
off-screen pixmaps had to be disabled in order to stop corruption
of the background. It would have been great if Suse had disabled
that by default.
