MGA G200 issue in 6.12 and up

I decided to upgrade to 6.14 on a system with a Matrox G200 onboard vga
(supermicro X9SCL).

I use this system via the BMC. When the mgag200 driver loads, the bmc
screen flashes between no signal and the screen. The rate seems to be about
1 second no signal and 1 second with signal.

6.12 and 6.13 both have this problem.

6.11 does not have this problem.

I have a monitor plugged into the vga port and it doesn't have this problem
on any of the kernels I've tried. Only the remote connection through the bmc
has this problem. I have booted the system with and with out the monitor
plugged in, it does not appear to make a difference.
