The linux ABI currently uses FPA: that's recognized to be a problem, given 
that FPA is not available for any "modern" processor.  ARM is currently 
working towards specifying a new EABI, and once that is complete, I'm 
hoping Linux will adopt that as its new ABI -- if they are going to 
change, better to change once than have several incompatible variants 
floating around.

If you really want to build a linux system with a different floating point 
format, then as you suggest, you can force the issue by passing -mfpu=... 
to the assembler.  I'm currently working on gcc patches to allow that (at 
present, selecting VFP word ordering on soft-float has to be done by 
hacking the config files).

R.
