One weekend? Nice :)

Oh I guess every VM hacker has seen this :) You might just copy the  
bit depth conversion routines from another VM.

I think you're the first one porting Squeak to a new platform after  
VMMaker. So there might be indeed some overly helpful features in there.

Or is it not VMMaker, but rather that the VM got more complicated  
because we rely a lot on modules nowadays? I'm not quite sure what we  
actually need for a minimal functioning Squeak port.

Sure, please, keep us posted!

And, to get the attention of most people interested in the VM (even  
those who do not follow squeak-dev closely) you should post to the vm- 
dev list, too:
