X Radeon driver

[sum]

Hey all, I've been searching for a few days now and I'm struggling with the radeon driver which comes with X.

Here's my GPU:

vgapci0@pci0:1:0:0:	class=0x030000 card=0x0490174b chip=0x5b621002 rev=0x00 hdr=0x00
    vendor     = 'ATI Technologies Inc'
    device     = 'RV380 RADEON X600 Series 265MB'
    class      = display
    subclass   = VGA
vgapci1@pci0:1:0:1:	class=0x038000 card=0x0491174b chip=0x5b721002 rev=0x00 hdr=0x00
    vendor     = 'ATI Technologies Inc'
    device     = 'Radeon X600 Series - Secondary'
    class      = display

Heres the moinitor. Xorg correctly identifies all of the monitors attributes.

Here's the Xorg log:
The warning in bold is what I think is the major problem, I don't know what it means fully though, or how I can fix it - any help or suggestions much appreciated.
