Is this buggy FPU only in the 200MHz versions of the ARM9-based TS-boards, or 
does it also affect the 250MHz and 500MHz?

Can I disable FPU usage all together in the kernel and/or clib so I'm certain 
the FPU won't be used?

I was initially interested in the TS-7260 but perhaps it's worth choosing 
TS-7550 instead.  Unfortunately it doesn't have any ADCs...
