any particular reason why your using the vesa driver on what seems to
be a fairly recent ATI card instead of the ATI specific drivers? Perhaps
the vesa driver doesn't work as well with power management(never used it
myself for very long).

I'd try the ATI drivers and see if it fixes the behavior, you'll probably
get much better performance at the same time, with perhaps a bit less
stability depending on what you do.
