Description of problem:
mga driver that we ship in RHEL 5.3 do not support higher color depth other than 16 so VIDEO will always FAIL since the minimum requirement is > 16. Since most of the server in the market using mga so please advice
It seems that the mga driver does support 24/32 bit color depths. Some hardware may fail to support this due to inadequate RAM. Closing this as NOTABUG, since HTS should fail these systems.

...probably a RHEL/X driver bug or still a hardware issue but re-opening for now under hts.

Closing as per comment #23.

Red Hat has hardware as do our on-site partners.
And per comment #2 regarding certification, Rob L spoke with Kevin M.

So if the problem is indeed a RAM limitation on the video card, I agree this should be closed as CURRENT RELEASE. If not a hardware limitation, then we need to consider modifying the driver to support 24 bpp.
Trying to fix this problem on RHEL5.4 with great effort.
Keep you posted.
