Linux 2.2 ignores several FP instructions althogether if there is no
FP emulation available - currently the list is:
wfs
rfs
ldfe f?, [sp...]...
ldfe f?, [fp...]...
stfe f?, [sp...]...
stfe f?, [fp...]...
These are the instructions that typically would be used to stack/unstack
FPs over function alls and initialisation of the FP status word.
Any other instruction will cause a SIGILL to be sent to the process.
This should be sufficient to allow insmod to load whatever FP emulator
you choose, whether that be the Acorn FPE or the NWFPE. Currently, my
test setups involve replacing NWFPE compiled into the kernel with the
AcornFPE (insmod in inittab).
