While we're on the subject... I understand that certain FPUs support 80-bit precision. Is there any way to get at that? Or is this going to require FFI too?

Perhaps you want Foreign.C.Types.CLDouble ?

(Or do you really want to ensure that it's 80-bits regardless of platform and the whims of the C compiler?)

Yep, that'll do. :-)
