Not that I know of any, but for reference, the PlayStation2's EmotionEngine
Processor (R5900) has a fixed Impl value of 0x2E.

[oliver@asuka tmp]$ cat /proc/cpuinfo 
cpu                     : MIPS
cpu model               : R5900 V1.4
system type             : EE PS2
BogoMIPS                : 392.40
byteorder               : little endian
unaligned accesses      : 0
