I had a closer look:

Symbol: XENO_HW_FPU [=n]
   Type  : boolean
   Prompt: Enable FPU support
     Defined at arch/powerpc/xenomai/Kconfig:24
     Depends on: XENO_OPT_NUCLEUS [=y] && PPC_FPU [=n]
     Location:
       -> Real-time sub-system
         -> Nucleus (XENO_OPT_NUCLEUS [=y])
           -> Machine

It depends on PPC_FPU and therefore the option is not selectable
for a system without FPU. I'm really surprised that it is on
for your 405GP board. Maybe your BSP is broken.

Wolfgang.
