[Xorg-driver-geode] [PATCH 1/2] Revise the entry for 1024x600

[Huang, FrankR]

*Change the entry of 1024x600 from 3 to 7(That will not affect the entries from
3 to 6). And BIOS should set the VG_FP_TYPE bit[5:3] to 7.
*Use 1024x600 at 80 instead of 1024x600 at 60 parameters to support more 4:3 resolutions
