Great documentation, thanks!

The Rev 5.0 board has J251 "PDN EN" (apparently documented nowhere
except for the DULG) for that purpose. When set, Pin 14 is grounded.

But it didn't help much. I took random shots at the CORALVO[RGB] signals
on the extension connector, and even there, the red and green channels
are only half the amplitude as the blue channel with a typical
grey-on-black linux startup screen. The picture also looks dim-blueish.

I think I'll try the board in a Windows box in the next step ...

We're running qte 3.1.1 on the Asilient chip (cpu is MPC8245),
and we didn't have to hack Qt for this, hmm ...
