The nv driver only supports XRandR 1.2 using NV5x GPUs (8xxx and 9xxx series 
cards).  The blob does not support XRandR 1.2 at all.  Nouveau does support 
XRandR 1.2 and support for NV4x GPUs (6xxx and 7xxx series cards) is supposed 
to be fairly good.  So Nouveau is an option for you but it will likely take a 
significant amount of effort to get it running.

As far as I know the Intel GPUs are not available in an add in card so that 
would require a new motherboard & perhaps CPU.  But this would likely give you 
the most mature XRandR 1.2 drivers.

I don't know about the drivers for the ATI/AMD hardware.  Perhaps someone else 
could comment.
