Dual head t42 with Fedora 7, tricks?

[Gene Horodecki]

Hi there.. I was able to get dual-head working on my t42 (Radeon
Mobility 7500) working out of the box to a certain extent but still not
to my satisfaction.  Is there a trick to getting a different resolution
on each of the monitors?  I have a 1024x768 LCD screen and a 1600x1200
VGA monitor and I had hoped to use each to the fullest extent.  So far
it hasn't worked with either extended desktop (which I prefer) or with
the two desktop config.

Please help?  Thanks.
