I've tried nouveau in the meantime, but it takes over simpledrm (and 
changes the screen resolution and turns on the secondary display), so 
it's completely different. And it also works, at half the performance.

Oh, I was under the impression that simplefb was removed from the 
kernel. It turns out it just has `depends on (FB = y) && 
!DRM_SIMPLEDRM`, so it didn't show up in the config after I enabled 
simpledrm. Ouch.
Based on a quick test, simplefb fortunately still appears to work.

Thanks,
Zoltan
