hmmm, isn't n32 kernel a relatively uncommon way of setting up the new mips code? i'm not sure matt ever tested that properly, but it seems to me it should be capable of running o32, n32 and n64 applications, but matt should have a look at this..
(i'm pretty sure the designed method is to run n64 kernels and to have n32 userland default, with both o32 and n64 userland compat available.) .mrg.
