didn't really review the actual values for the table... supposedly this
is "write only table and never look again".
The rest is much better in this version.

I know this is in the commit message, but a comment in the .c or .h file
stating these tables are "given by the VESA C model for DSC 1.1" would
help the me from tomorrow to know what are those tables. Anyway, not
very important... just if you have to respin this.
thanks
