Comment(by dilinger):

 For those playing along at home, the following patches affect the DCON:

 Note that the logs show smbus timeout errors during suspend/resume.. And,
 the error case where the smbus goes screwy and we're forced to reinit the
 dcon.  I'd *really* like to know the cause(s) for that.  Dave also
 mentioned wanting to see traces..
