Subject: floating point usage within the kernel - howto ?

a local user has a need to do some Floating Point computations within
the kernel. I think this is not possible without explicitly
saving&restoring the FP register around the task, is this correct ?
And if this is true, is there any trick/asm routine to call to do the
saving & restoring of the registers ?

	thanks
