I don't believe that the bootloader for Acorn based hardware uses libsa (I 
may be wrong, and it'd be good to know)  All boots on currently supported 
acorn hardware goes into Riscos (no choice, it's where the roms are I think)  
The bootloader has to map things around.

Is there any major gain to doing so?

Have we plans in the near future to switch to ELF? (by near I mean next 
release, 1.6?)

Wouldn't a move not require the kernel to be ELF, IE userland goes to elf, 
kernel is a.out, and then eventually moves to ELF.  eg 1.6 userland to elf, 
1.7 kernel to elf?
