Subject: DDC on Thinkpad x220

Hi!
Thinkpad X220 should be new enough machine to talk DDC to the
monitors, right? And my monitor has DDC enable/disable in the menu, so
it should support it, too...
But I don't have /dev/i2c* and did not figure out how to talk to the
monitor. Is the support there in the kernel? What do I need to enable
it?
lspci says:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation
Core Processor Family Integrated Graphics Controller (rev 09)
Thanks,
Pavel
