backward only. For example, gcc likes to optimize access and uses double 
word load/store instructions until you specify -mips1. I don't know how many
binaries have it inside. I am afraid, almost all.

I don't thing somebody interested in entire port, because it's a quite 
specific machine which developed and produced in Russia. It has VME bus 
that is controlled by VIC068/VAC068 chips. Only thing that comes 
in mind is it's might help to port Linux to VME-based boards with a MIPS CPU.
There should be a lot such machines in the world... Anyway, I prefer to 
polish our code before posting a patch if nobody is interested to look at 
code soon.

Great, thanks.
