although not perfectly, kaffe does run on Mips, to be sure however I'm 
running a build of CVS right now on my r4400 system. I will post 
resulsts later here.

non-official implementation of MIPS can't have them. Usually gcc doesn't 
generate unaligned accesses, but kaffe could.

In any case, kaffe 1.1.4 is a bit old and you might try either 1.1.5 or 
even better CVS. But if the problem is your CPU then... you'll have
