Probably, because it's no longer relevant these days. It doesn't say
anything special.
The more surprising it is that BogoMIPS have become a benchmark for

Interestingly, my IP28 still shows the BogoMIPS reading in /proc/cpuinfo:
stuartl@indigo ~ $ uname -a
Linux indigo 2.6.10-mipscvs-20050115-ip28 #2 Sun Apr 3 08:24:18 EST 2005 mips64
R10000 V2.5 FPU V0.0 SGI Indigo2 GNU/Linux
stuartl@indigo ~ $ cat /proc/cpuinfo
system type : SGI Indigo2
processor : 0
cpu model : R10000 V2.5 FPU V0.0
BogoMIPS : 193.53

So honestly, I don't know what's happening with BogoMIPS. :-) What I do
know however, it isn't worth a cracker in terms of benchmarking value. ;-)
