So this usually works in userland, because Linux catches the exception,
but not in kernel mode?

What you describe sounds like something that can be fixed with some
flag (e.g. like -msoft-float).  Are you sure this isn't possible?

We're using stock gcc 4.3.2-1.1.  Could you point me to the commit that
fixed this issue?  I'd rather backport a patch than using a development
branch of GCC, if possible.
