I don't really understand much about the LaTeX font selection 
mechanism, but I suspect that changing the \encodingdefault may well 
affect things; that could well be why the ligatures and accents in CM 
text fonts get disabled.

FWIW, this is not really a XeTeX problem, strictly speaking; I think 
the actual XeTeX tool is working as it should. This looks like an issue 
of understanding how to configure LaTeX fonts and encodings, with the 
introduction of a new kind of fonts. (To check that XeTeX itself is 
handling the fonts OK, try the Plain TeX test I suggested; I believe it 
will work correctly.)
