As the hacker edition shows, quite many parts of the new software can be made to work - to some extent - but there are valid differences in certain things like DSP handling, which certainly aren't by no means trivial.
It is OS kernel responsibility to handle these hardware differences (and this problem is solved/workarounded by running old kernel in OS2007HE). Userland should really see little differences between 770 and n800 when properly implemented. Both of these devices have an ARM core, they use the same C55x DSP (Nokia 770 DSP is probably even more powerful than N800 as it is running at higher clock frequency), LCD controllers are very similar (N800 uses a newer revision of Epson chip). So fanoush is right, the differences are comparable to the differences between Pentium and Pentium II on desktop (which are also mostly handled in kernel, so nobody notices them).
