Not necessarily. Panning is certainly helpful, but the driver doesn't
even detect the higher resolution.
Given you have a dead old version of radeonhd, please try the current
1.2.5 one. It is also probably that you stumble over an randr bug in the
Xserver, as 1.4.2 is also ancient. To get more informative output in the
log also try starting X with -logverbose 7.
If the newer versions don't help, try posting on the radeonhd mailing
list - see http://www.x.org/wiki/radeonhd
