Unfortunatly I haven't tried using the fpu emulation, I'm just
relaying to you what I've been told when I pursued it hoping to save ram.
After finding out it would only shave about 4K off of glibc I abandoned
the quest. I determined it was just not worth the hassel for such small
gains and applying my efforts elsewhere would yeild greater savings.
I don't know of anyone who has tried it lately, so the bugs may
no longer exist. Wolfgang Denk (who's opinion I hold with high regard)
has said that he could get it to fail with the "ls -l" command as I
recall.

Exactly why do you want to use fpu emulation?
Hope I'm helping
