You need to have xserver-xorg-video-sis installed --- I´d remove the
other xserver-xorg-video-* packages.

The "sis" has already been tried, though, as you can see in the
logfile:


(II) LoadModule: "sis"
(II) Loading /usr/lib/xorg/modules/drivers/sis_drv.so
(II) Module sis: vendor="X.Org Foundation"


Later it´s unloaded. It looks as if the xserver gets confused because
it loads arbitrary modules and cannot figure out the capabilities of
the screen:


(II) VESA(0): <default monitor>: Using default hsync range of
31.50-37.90 kHz
(II) VESA(0): <default monitor>: Using default vrefresh range of
50.00-70.00 Hz
(WW) VESA(0): Unable to estimate virtual size
(II) VESA(0): Not using built-in mode "1280x768" (no mode of this
name)
(II) VESA(0): Not using built-in mode "1024x768" (no mode of this
name)
(II) VESA(0): Not using built-in mode "800x600" (no mode of this name)
(II) VESA(0): Not using built-in mode "640x480" (no mode of this name)
(WW) VESA(0): No valid modes left. Trying less strict filter...
(II) VESA(0): <default monitor>: Using hsync range of 31.50-37.90 kHz
(II) VESA(0): <default monitor>: Using vrefresh range of 50.00-70.00
Hz
(WW) VESA(0): Unable to estimate virtual size
(II) VESA(0): Not using built-in mode "1280x768" (hsync out of range)
(II) VESA(0): Not using built-in mode "1024x768" (hsync out of range)
(--) VESA(0): Virtual size is 800x600 (pitch 800)
(**) VESA(0): *Built-in mode "800x600"
(**) VESA(0): *Built-in mode "640x480"
(==) VESA(0): DPI set to (96, 96)


So what happens when you purge all xserver-xorg-video-* packages
except for xserver-xorg-video-sis?
