Well here's the story: a few days ago my video card broke, so I'm without
X and such, and using a spare 486 box on the freebsd console. Out of lack of
other things to do, I did most of the porting of one of the screensavers in the

You can't safely do FP instructions in the kernel. I do not
believe the FP context is saved/restored between processes in kernel
mode, only from user mode. The kernel saves and restores the fp state
in the few places it uses FP instructions (for memory copying).
