commit 25aec295958292ceca73fbce446ccc05bc6f3c39
Author: Vladimir Serbinenko <phcoder at gmail.com>
Date:   Sun Jan 5 00:51:12 2014 +0100

    X230: current tree as-is.
    
    Known issues:
    - No keyboard backlight (thinklight works)
    - No S3
    - EHCI output sometimes get "stuck" until key is pressed after sysagent execution.
    - no S3
    - MRC fails if MRC cache is supplied. For now MRC cache is disabled.
    - MRC sometimes hangs with message:
    System Agent: Initializing PCH
    {433e0f9f-05ae-410a-a0c3-bf298ecb2
    
    So a watchdog is reenabled to reboot if this happens
    
    Not tested:
    - ultranav
    - fingerprint
    - dock
