: I believe so but how would I know for sure? If, using fbset for example,
: I set the depth to 1bpp, then am I inherently using fblin1.c?
Yes, the code in scr_fb.c selects the driver from the returned
fb info

Yes, as long as you can somehow get the adjacent three pixels from
the controller. Otherwise, you'll have to store everything in an
internal ram buffer as well.
