[ddccontrol-devel] Support for new intel chipsets

[Dmitry G. <gur...@dg...>]

Hello.

Do you plan to support i96x chipset series ?

I have laptop with intel x3100 chipset and ddccontrol doesn't work with it by 
default, because memory region with control registers has size 1Mb instead of 
512K (and its ID is missing in intel810.c).

I haven't read intel documentation carefully yet, but this in this document 
http://intellinuxgraphics.org/VOL_3_display_registers.pdf  written that this 
chipset has 8 GPIO registers at the same addresses as in i810 chipset.

With patch in attachment dcc controls on monitor, connected to VGA output 
works fine, but I not good in graphics adapters programming, so don't know, 
is it correct.
