Sure. Here are some suggestions to start with:
Start by posting a bug report that includes details of the crash to
Launchpad so that the Ubuntu maintainers can investigate the problem.
Include all the relevant details, such as the errors output from the X
server, in the report. Those will help them track down the issue.
Consider posting a copy of those details here along with the errors.
It could be that once we see the cause of the issue we can help you.
Definitely report the fact that your system will lock hard when used
with the VESA driver, coupled to mouse movement. That is significantly
wrong -- since the VESA driver simply switches to an appropriate video
mode, then does all the work in software.
Ideally you should try to capture the error report there as well. Try
logging in from another machine over the network and watching the kernel
and X logs.
If that isn't sufficient get hold of a serial cross-over cable and use
that to monitor the same logs; being less complex the serial device may
succeed where the network fails.
The last thing you should do is take your problems with the driver from
"viaarena" to the appropriate forum. Since that is supplied by VIA, as
I understand it, they are the best people to provide technical support
on their private driver.
