   8 commit 6053d3a4793e5bde6299ac5388e76a3bf679ff65 upstream.
   9
  10 In order to support the 1024x600 panel on Yeeloong Loongson MIPS
  11 laptop, the original 1024x768-16 table was modified to 1024x600-16,
  12 without leaving the original. It causes problem on x86 laptop as
  13 the 1024x768-16 support was still claimed but not working.
  14
  15 Fix it by introducing the 1024x768-16 mode.
