 >  * with that viafb fix, the dcon gets unfrozen too early - before the
 registers are reset - showing a nasty orientation glitch. After many wrong
 turns, we found that it's happening in OFW. James Cameron built a roughly
 patched OFW that doesn't unfreeze the dcon, and it fixes the problem. Now
 we need a proper patch & release of OFW.

 this is probably the root cause behind #9631 as well.

 >  * during the above investigations, we commented out a dcon unfreeze
 that happens in the kernel driver olpc-dcon -- unclear whether we need it
 i believe the dcon driver is the right place for this unfreeze.  or, at
 least, it's always been there, and other than the glitch, it works fine.
 no unfreeze is done at user-level, so without the one in olpc-dcon, we'd
 have to invent something new.
