Agreed. And it's happening. I got -current going on gxemul!
There are some mips1 vs mips3 bugs in trap handling and some debug
code that assumes mips3. Moving on to physical hardware ...

segment  0 start 00000000 size 05000000
phys segment: 0x5000000 @ 0
adding 0x38a000 @ 0x476000 to freelist 1
adding 0x4800000 @ 0x800000 to freelist 0
