  I think I did go over the mailing list limit of 40K, when posting
the Xorg.0.log of a xserver compiled with debug info and from
"startx -- -logverbose 99", and the email to the list is waiting
moderator approval :-)

  Thanks, I will test it tomorrow. BTW the "magic" option for the via
driver is:
  Option "DisplayHardwareLayout" "TTLLCD"

  It works with the vesa driver, but the bios only reports the resolution
640x480 at 8, 16 and 32 bpp, i.e. it is scaling from 640x480 to 800x480.
