This comes out to 72.5Hz refresh, I think there are a few more lines
than in U-Boot but it is still a big jump. Maybe someone can test this
for flicker, I didn't know a good way to fill areas of solid colour with
what is in the rootfs in Linux.

fix-glamofb-flicker-72hz-refresh.patch
From: Andy Green <[EMAIL PROTECTED]>
Move video timings from 60Hz to 72.5Hz by removing needless blanking pixels.
Also correct the video clock reported by X since Carsten said it showed
50Hz refresh, presumably due to wrong PCLK data in the same struct.
