I've reported it and got no response. I've also reported the equivalent
MetroX problem to the MetroX authors and got some limited response then
silence. Something has changed in the bank switching logic in the Cirrus
or maybe generic SVGA server between 3.1.2 and 3.2.x. I don't currently
have time or really enough knowledge of the X server innards to try and
hunt down the problem.
If the worst comes to the worst and Metrolink are at the next Linux expo
I'll try and get them to bring along a MetroX debugging kit and take the
machine over for them to play with.
It does also seem to be specifically a PC110 problem. The same driver is
reportedly working on other systems
