So far everything including the BCM4321 card is working, however, the OEM ATI Radeon X300SE (RV370) is not recognized. When I go into system details the card comes up as unknown.

When I run lspci the card shows up as:

01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV370 5B60 [Radeon X300 (PCIE)] 01:00.1 Display controller: Advanced Micro Devices [AMD] nee ATI RV370 [Radeon X300SE]

I have attempted check Additional Drivers but the card does not show up as needing a driver.

So far this is causing the system to run warmer as the processor is doing a bit of the work to run Unity and any full screen videos tend to be rather choppy.

Is there an available driver that will fix my issue and what is the install method?

I am not scared to run a terminal so no worries there, as long as I have instructions, I can find my way.

I am running under 12.04 LTS Kernel 3.2.0-25-generic-pae
