When you boot with check-key OFW already unfreezes then DCON, so the 
kernel doesn't need to do it anymore. Brightness setting - which you 
reported as non-working - is also done using the DCON, so from my side 
it's still looking like a DCON driver issue.
Can you post the output of "dmesg |grep -i dcon", please? If the DCON 
driver works, it should say something like:

[    4.213218] olpc-dcon:  Discovered DCON version 2

If it doesn't output anything at all, there's either no DCON driver 
present or it doesn't get invoked, the latter of which would be #9687.
