A G200SE_A rev 1 user reported that prior to v6.0, he was able to get Xorg working at 1440x900@60Hz. This somehow bypassed the bandwidth test in the driver. After v6.0, and the driver refactor, it's no longer possible. So increase the bandwidth, as the hardware is able to do it. In mgag200_calculate_mode_bandwidth(), the bandwidth for 1440x900@60 is 30318019, while 24400 * 1024 = 24985600 and 30100 * 1024 = 30822400. Raising the bandwidth from 24400 to 30100 is enough to allow this mode.
