Well, thanks to a very informative post on the ubuntu forums:
http://ubuntuforums.org/showthread.php?t=1152121&highlight=fglrx , my
problem is now fixed.

To do a bit of copy/pasting from that post:

Edit /etc/ati/amdpcsdb
In the section labeled [AMDPCSROOT/SYSTEM/DDX]
Add this:  

EnableRandR12=Sfalse

and in xorg.conf
add this:  

Option      "EnableRandR12" "false"

I believe I rebooted at this point.

I then set up pairmodes using the aticonfig command:

sudo aticonfig --add-pairmode=1152x864+1440x900

then it was a matter of loading up Catalyst Control Center, and
activating Big Desktop, and then setting the overall screen resolution
to 2592x900.

Presto!  Completely working and fast compiz.  I hope this fixes your
problem, Graham.

Cheers,
Ryder
