omapfb how to?

HI,

I'm trying to enable omapfb and prvsrvkm kernel modules in order to
test beagle's acellerated Opengl rendering capabilites.

I have downloaded SDK and drivers from TI's website and I followed the
instructions of installation.

All the modules were installed and initialized correctly. However,
when I start X i have the following error:

omegafb(0): FBIOBLANK: Invalid argument

Well, from now on I don't know what can be wrong.

Any tips?

Thanks,

Nuno
