Yes. See below for details.

ATI chipsets, particularly the "mobile" laptop versions, constantly
change PCI ids. This has been causing us a great deal of pain.

This was the most-discussed topic amongst the LTSP developers at
LWCE NY.

We have a couple of ideas on how to tackle this problem, but no
working code as of this moment. (as far as I know, Jim may have
coded it since we last talked ;-)

The simple solution, probably the one we will try first, is to
drop back to the vesa driver. Try setting XSERVER = vesa  and let
us know if it works decently on the two that you are having problems.
