That's an option of course, but not necessary.  The distribution 
supplied driver very much does support and work with resolutions 
as high as the hardware supports.  I use 1600x1200, and test with 
1920x1440 and 2048x1536 as well.  So changing video drivers isn't 
going to likely change anything.

Not really tricky at all.  The X server log file will indicate 
directly what modes were rejected and why for every known built 
in video mode the X server supports.  That information tells you 
why a video mode is not available, and is almost always due to 
misconfiguration or inability to autodetect hardware properly 
such as from using a KVM switch that blocks DDC, or having the 
monitor turned off during X server startup, etc.

... on the machine should result in a working video configuration 
with ability to use up to 2048x1536, although I don't remember 
what resolutions our config tool presents to users off hand, the 
X server and radeon video driver can max out the card's 
capabilities.  All of this is assuming a CRT monitor.  DFP panels 
may or may not work similarly, don't know as I don't have such 
hardware to test with.

Hope this helps.
