Its not the use of floating point in the kernel thats the problem.

	I would like to "emulate" the fpu in the kernel so I can
compile glibc and everything else with fpu instructions to save
ram. I have been told however that there are "issues" with this
approach, and the only way to go is to emulate the fpu in the
kernel and compile everything with soft float. What I want to
know is what these issues are? (accuracy,segment_fault,etc..)
