It does save us about 5% though, which is quite substantial when you're
talking about fitting a kernel on a boot floppy. For the past few kernel
versions it has made the difference between being able to base
installation floppies on the standard Debian kernel (generic 486 flavor)
or having to come up with radical new solutions.
