It's modprobe(8), and all the man page says is that it returns
non-zero if you try to remove or insert a module it can't find.

Explicitly checking for an os.system() return value of 1<<8 seems like
a pretty bad idea to me, since there's nothing in the modprobe docs
that gurantees it will return 1 under some particular conditions.
