I think I have the same card. lspci:
01:00.0 VGA compatible controller: VIA Technologies, Inc. UniChrome
Pro IGP (rev 01)
The x11 driver calls this a VT3344 (/var/log/Xorg.0.log)
(--) VIA(0): Detected VIA VT3344 (VM800) - EPIA EN.

Me too. For 2D I could fix most of the stability problems by adding the
following options to my xorg.conf ("Device" section, see 'man 4 via'):
Option "NoXVDMA" "true"
Option "NoAGPFor2D" "true"
Option "DisableVQ" "true"
So I guess, the problem might by AGP/DMA related.
Another problem was that high-resolution movies (>= 720 lines etc.)
won't be up-scaled correctly by XV (using 1650x1080 video mode). Using
the experimental driver branch fixes that specific problem for me:
svn co http://svn.openchrome.org/svn/branches/experimental_branch
3D still doesn't work reliably with some applications. 'torcs' crashes
my machine. Lucas (in CC) has the same graphics chip and reports
similar problems on a Debian system (I'm using Ubuntu 7.04)

That would be a very good thing :)
One reason for me buying a Via C7 board was the graphics chip with
open-source drivers available. But the current situation is somewhat
disappointing.
best regards,
