Linux version 3.5.0-rc2 (tsbogend@solo.franken.de) (gcc version 4.3.1 (Debian 
4.3.1-2) ) #1 Thu Jun 14 12:05:29 CEST 2012

this version (current git from two days ago) boots for me with serial console
up to a login prompt:

mips:~# cat /proc/cpuinfo 
system type             : SGI O2
processor               : 0
cpu model               : R5000 V2.1  FPU V1.0

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
