I'm using the same chipset (although not onboard).  I've only ever got
it running in 24-bit colour; it doesn't support 32 and 16 looks ugly.
This is really annoying because the xpm library has a bug in it for 24
bit colour so all pixmaps displayed using it come out all distorted.
Perhaps this is part of the problem you're having?  Otherwise it could
be because your video card is setup wrongly as Matt suggested.  There
are some options in the Device section of your /etc/X11/XF86Config file
for this particular video card and I remember having to fiddle around
with them a bit before setting them otherwise I got distortion.  Mine is
set as follows:

Section "Device"
    Identifier  "SiS 6326"
    VendorName  "Unknown"
    BoardName   "Unknown"
    VideoRam    4096
    # Option "no_accel" # Use this if acceleration is causing problems
    # Option "fifo_moderate" 
    # Option "fifo_conserv" 
    # Option "fifo_aggresive" 
    Option "fast_vram"
    Option "pci_burst_on"
    # Option "xaa_benchmark" # DON'T use with "ext_eng_queue" !!!
    # Option "ext_eng_queue" # Turbo-queue. This can cause drawing 
                             # errors, but gives some accel
    # Insert Clocks lines here if appropriate
EndSection

Perhaps you may want to compare the similar section in your XF86Config
file and see what options you have set.

Hope this helps,

Christian.
