Apologies, like Cameron states this does seem to be radeon KMS related.
After switching to a VT after booting with nomodeset appended, I
realised this parameter has no effect. Booting as Cameron does, with
radeon.modeset=0 vga=771 resolves the problem.

When enabling the 2nd monitor with KMS disabled there is a dialogue
appearing titled "Monitor Resolution Settings" asking if we want to
change the virtual resolution, this does not appear when KMS is enabled.
