Ah, modular is *so* much nicer to work with.  I was able to just rebuild 
my ATI driver and test it out without too much pain.

You mentioned that this might help with the VT switch problem on my 
pbook.  Unfortunately, it doesn't.  I have MergedFB off, but other than 
that I'm using stock settings.  The server seems to run ok, but if I 
switch to a console VT (ctl-alt-f1) then back to the X server 
(ctl-alt-f7) the machine hangs in a bad way and display gets corrupted 
(turns rainbow colors).

Is this a known bug?  Has anyone else seen this behavior?

Thanks,
Jesse
