post resume register tries.

This is after I suspended and resumed. Please note that HDMI-0 returned
automatically. 

ken at ken-K53TA ~/tmp/radeontool $ sudo ./radeonreg regs dce4 >
regs.broken.0-lvds-resume
ken at ken-K53TA ~/tmp/radeontool $ env DISPLAY=:0 xrandr --output LVDS --off
ken at ken-K53TA ~/tmp/radeontool $ sudo ./radeonreg regs dce4 >
regs.broken.1-lvds-resume-off
ken at ken-K53TA ~/tmp/radeontool $ env DISPLAY=:0 xrandr --output LVDS --auto
ken at ken-K53TA ~/tmp/radeontool $ sudo ./radeonreg regs dce4 >
regs.broken.2-lvds-resume-auto


At this point i rebooted after unplugging cable... it's an odd state to haft to
login and issue xrandr over ssh but the lvds returned just like the previous
entry.
