It probably is not the right refresh rate, the problem is how do i get
the right refresh rate.
I need a hack to get my 1280x800 panel working, because the BIOS only
supports 1024x768 and 1280x1024 panels on the LVDS port. If i don't have
the hack it doesn't flicker but it only allows 1024x768 in the top left
corner of the LVDS-Panel. When i apply the following patch, i get my
full 1280x800 resolution. With the modesetting branch this patch also
works, but it doesn't flicker. Since it is a direct panel without a OSD
i can't really check the refresh rate, but the CRT has 60Hz and it
almost looks like the LVDS-panel only have half of that.
