I'm all for removing it, so long as i386 libc is fixed to support 
soft-float builds.

For the record, I have a local port of NetBSD for the Linksys WRT54GR, 
which has an RDC-something-or-other SoC:

 cpu0 at mainbus0: (uniprocessor)
 cpu0: Cyrix 486DLC (486-class)

Needless to say, it has no FPU and gets nowhere with MATH_EMULATE. 
Soft-float userland mostly works.

I might still have the soft-float fixes lying around...
