I tried to debug this a bit, but I'm having trouble - 

I get "exceeds panel dimensions" for *every* resolution in Xorg.0.log, reason
being MODE_PANEL is being thrown in xf86ValidateModes().

Which leads me to believe that for some reason, xf86ValidateModes() 
or more specifically xf86InitialCheckModeForDriver(), line 1620
somehow forgot that the panel size was 1400x1050.

Now, that message apparently would originate ATIValidMode() in ativalid.c, line
103 or 109 as far as I can tell, but when I try to get what it thinks the panel
resolution is at that point with some ErrorF()s, id doesn't seem to be making
its way into the driver.

So, maybe ATIValidMode() isn't being compiled into the driver?

Found some info that suggests that missing/wrong video BIOS information may be
the culprit, please see  http://mgalug.org/suse/9.2.

I'd be more than happy to try anything you'd suggest.
