Hello everyone,

	I've been told on this list that there are problems fpu emulation
in the kernel. I was curoius as to what the errors are and the aftermath
(pun intended) that occurs when they are encountered. ( Like are the
values off a little bit or a lot, does it cause a kerel panic, does it
block interupts, does it unleash a terible monster that will destroy the
universe, etc... .)

	I'm also very supprised that Motorola and IBM haven't dedicated
some resources to address these problems since their fpu-less chips are
often used in linux designs.

thanks in advance,
