So some of the stuff running on the 770 using os2007on770 has been compiled
for the N800 (i.e. using ARMv6)? 

This would be interesting to know, as it would indicate that it may be
possible, admittedly with effort, to get other (N800) apps to run by
implementing vfp illegal instruction exception handling in the kernel (in
much the same way as fpa works). I had expected there to be more instruction
differences considering the number of binaries and my assumption of their
complexity (and therefore chance of inclusion of the new armv6
instructions).

Cheers,
