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.
