Thanks for all the help.
It is indeed bad that fontspec just overrides lucbmath and euler  
definition of accents and so on, which is why the \if.. \fi was there  
to begin with. But based on what we've got I've a feeling that it  
shouldn't be too hard now to fix things up. Just a trawl through the  
relevant packages to see where the clashes lie and fix it up  
\AtBeginDocument, provided fontspec is loaded last.

I'll do as much as I can as soon as I can :)
