[sanjay anvekar]

Hello,
     I have Intel GMA500 board with integrated graphics.Display of 800x480 
resolution is interfaced to
the board.I would like to enable Kernel Mode Setting to achieve this resolution. 

So please can anybody let me know which Linux Kernel option need to be selected 
in order to achieve 

this.
I am using Kernel 2.6.36.2.

Thanks & Best Regards,
Sanjay
