  Still did not "properly" work. I applied only VX800_2.patch on a fresh
checkout. Instead of using no options, added "NoAccel" "On". It seens
to be messing on the rgb masks, as colors are completely wrong, and
xwud -in foo.xwd in another host, from "xwd -root > foo.xwd" shows
correct color.

  When trying to exit, by Exiting the current session in KDE:
-%<-

-%<-

  And the computer is completely locked, needing a hard
reset (cannot interrupt gdb). My guess is that it is
in some function called by VIACloseScreen(), but
the computer is completely locked...

  I also tried using option ShadowFB, as it was an
alternative in another computer with VIA video, that
worked, while NoAccel didnt... But same result, complete
lock at exit.

Only this line was not added in logfile,
printed to my xterm from where ssh'ed

-%<-
Synaptics DeviceOff called
-%<-
