I've never claimed that MorphOS lacked 3D support! I even had a PegII and I liked it! I have claimed that it lacked the 3D functionality that was available on my PC especially in light of the fact that MOS is hobbled with decades old Radeon cards, just like OS4!
As for the bullsh@being slung here, I think the above diagram was lifted from the paper published at the link below and modified for the sake of "convenience", by dammy and terminills, to add more smoke and mirrors to their argument that they've somehow merged an Aros kernel with a Linux kernel. So to be specific, here's the link which clearly shows that this Arix/Linux merged kernel is bullsh@t!

That's pretty weak. You didn't spend 30 seconds on google to find something to trot out did you? The ARIX breakdown graphic looks more stylistically similar to some of the NTOS kernel high level hierarchy diagrams, which isn't saying much because everybody uses the same style to depict this stuff. You've never seen this kind of stuff before, have you? I don't believe your educational credentials for one second.
