Can you describe how this is handled on the Alpha?
The primary problem is the differnet calling sequence for o32 and N64.
As it looks we'll be able to use either the o32 function or the native
syscall to implement all of the necessary N32 syscalls.
The question is if we want to reserve another 1000 entries in our already
huge syscall table for N32 or if we got a better solution ...
