Here's the offending code in glibc:

that's what kills us.
How's this for an idea - what if we could cook up a little binary that
will do an LD_PRELOAD of the __setfpucw to something harmless? It
could then be used to insmod the FP emulator, or call any other
command. Is that possible?
I think that you should probably discuss this with Ulrich Drepper
before doing it. There was a long discussion about this very issue
(setting the fpu control word at every program startup) on the
linux-kernel list a number of months ago, and I don't remember exactly
what the conclusion came to be.
