Thanks!

Well, that rules out the new driver theory.

And here's the OF node:

... I haven't seen that one before. Unfortunately it hasn't been set up
by OF ( I should have thought of that before asking... )
The ROM range is huge - usually it's 64KB or sometimes 128KB, but this
one is 16MB. Can't be the problem though, we don't mess with it.
I kinda expected some weirdo Apple onboard video thing, most of which
don't play nice with OF, but that's not the case here either.

So, can you please send me the ofctl -p output from the 5.0 system
running with the graphical console, so I can see what properties OF
sets on the device node? The theory I have left is that something is
missing or different there, which we used to deal with but the code has
bitrotted.
( Just that node is enough, the rest should be more or less identical )

Genfb needs the address, width, height, depth and linebytes properties
set in order to work( basically, framebuffer address and geometry )
Some devices ( like certain Apple onboard video things ) don't set
these even if the device is otherwise set up. We have some workarounds
for some of them but they haven't been tested much, mostly for lack of
people with the right hardware.

have fun
