- The kernel's math emulation allows you to run programs which use
- floating point math. Unless you don't have _any_ fp math in _any_
- program, don't leave it out. But, and I think you can trust me on this
- one, you won't have particularly many useful programs then. GCC needs
- it, for example.

- I think that the space and time savings for not having the math
- emulation in the kernel are negligible.
