The via driver (X server) is supposed to take care of closing down and
cleaning up everything it has used when its CloseScreen function is
called.  I don't know if you're seeing a bug in the X driver or the
kernel driver.  Server reset is often a poorly tested case, but it is
usually straightforward to fix the problems that arise there.

I'm not aware of anyone specifically working on the via driver for XFree86.
Why not take it on yourself?
