var.accel_flags / FB_ACCELF_TEXT is something different: you need to be able to
disable hardware acceleration before your application touches the accel engine.

That was true in 2.4, I don't think this can apply reasonably well in 2.6.
In fact, from experience, the var tends to be "lost" easily, I'm not sure
why exactly.

On the other hand, I tend to think that if you have a KD_TEXT console,
accel is under fbcon control, if you have a KD_GRAPHICS console, then
the accel engine is under you control. I don't think any else make any
sense in fact

You're right, I forgot about that.

We really need to simplify all of that stuff, it's way too messy at the
moment.

Agreed.
