Unable to use 2560x1024 bigdesktop res since update to Catalyst 8.5-1

Can someone tell me if I've missed something?

I just did a system upgrade which included the Catalyst package and now I don't
seem to be able to set a 2560x1024 BigDesktop resolution. The options I have are
seemingly for single widescreen monitors. I have two 1280x1024 monitors side-by-side
which worked fine upto this update. Why has this resolution been dropped?

(Not sure at this point which config files/ settings are going to be relevant so if anyone wants
to see a config file, if it seems like my system then please, do ask)

Is it a package issue?

Many thanks in advance
JamesR

EDIT:
P.S Sorry forgot to mention - I have an ATI Radeon 9600 256MB/AGP Card.

Never Mind, All fixed.

I Forced the resolution within the xorg config file, for some reason it guessed wrong ??
To anyone that finds the same issue, you can force the resolution for EACH monitor like so:

bash# aticonfig --dtop=horizontal --resolution=0,1280x1024 --overlay-on=1

That will add the Mode line to your xorg.conf.

Cheers :-)
