I haven't seen your error messages in detail but I have seen a couple  
of similar problems after the etch-lenny upgrade. please see if the  
proper drivers are installed. i found that the xserver-xorg-video-*   
packages are generally missing after the upgrade. please try  
installing them, esp the ones for your graphics/video card.  
xserver-xorg-video-all should do for most cases.
hope that helps,

I have checked, and most of the xserver-xorg-video-* files are  
installed.  Specifically, xserver-xorg-video-all,  
xserver-xorg-video-sis, and xserver-xorg-video-vesa are all installed.   
How do I instruct xorg to use a specific driver.  The current xorg.conf  
file makes no mention of the driver to use.  I tried adding the line  
from my old xorg.conf file, to use the vesa driver, but then I am back  
to X simply not loading.  Is this information kept in a different  
location now?  It may well be that if I can get X to use the vesa  
driver, as it did before, that these problems, at least, will go away.   
Then I can concentrate on others, like my digital camera.
    
AFAIK, it should still work to put
    Driver    "vesa"
into the Device section of /etc/X11/xorg.conf; maybe the newer vesa
driver has a problem with your chipset. It might help to look at the
output of
grep -E '^\((EE|WW)\)|drivers' /var/log/Xorg.0.log
after starting X in the two different configurations (with and without
trying to enforce using the vesa driver). This should at least give us a
better idea about the reason of the crashes with vesa and which problems
the sis module might have.
