Is this still an issue with a newer version of the driver?

Yes. I am having this exact error message with a live Fedora 20 DVD on a Dell OptiPlex 780 with a PCIe ASUS Radeon R7 240 video card. The desktop never comes up.

I am unable to provide further information as I have been unable to install linux due to this issue.

There does not seem to be a way to disable the onboard video in the BIOS on the OptiPlex 780. The only options are "Auto" and "Onboard/Card". There error happens no matter which option is selected.
