As it turns out, the ATI FirePro 2460 works, but it's too slow with the
standard
radeon driver for our application.
I tested an NVidia NVS 510 with both the standard nouveau driver, and the
proprietary kmod-nvidia, nvidia-x11-drv rpms from elrepo. The two gave very
similar quick response on our application, so we've decided to use the
standard
nouveau driver.
Of all the cards I've tested, the 510 is the best.
xorg-x11-drv-nouveau-1.0.1-3.el6.x86_64
lspci shows
01:00.0 VGA compatible controller:
NVIDIA Corporation Device 0ffd (rev a1)
The rest of the info is the same as shown above.
