I've done so, and could see that the fonts in TeX Live 2007 (backup)  
have version 1.011 and in TL 2008 1.103. The latter fonts have much  
more lookup tables, and also liga tables:

  9:	10:  	12:	13:
f_f	f_i  	f_i	f_k
f_l	f_f_i	f_f_i	f_i
f_f_l		I_J	f_f_i
		i_j	

The sorting in the tables changes when I select Unicode or alphabetic  
in FontForge. I have no idea what this all means, but for me, as for  
Pander, the ligatures test works in TeX Live 2008. *When I use this:*


	\documentclass[12pt]{report}
	\usepackage{fontspec}%, xunicode, xltxtra}
	\fontspec{TeX Gyre Termes}
	\begin{document}
	
	\fontspec[LetterSpace=25]{Hoefler Text} Ghazālī lālīlū lalilula l 
\=al\=il\=ul\=a
	
	\addfontfeatures{Mapping=tex-text}\addfontfeatures{Ligatures=Common}
	IJ ff ffi ffl fi fk fl ij
	
	\end{document}

It uses Hoefler and CM ... Removing the Hoefler line I get:

	Package fontspec Warning:
	    \addfontfeature(s) ignored;
	    it cannot be used with a font that wasn't selected by fontspec.
	This warning occured on input line 12.
	
	Package fontspec Warning:
	    \addfontfeature(s) ignored;
	    it cannot be used with a font that wasn't selected by fontspec.
	This warning occured on input line 12.

and the font is Latin Modern. Using

	\documentclass[12pt]{report}
	\usepackage{fontspec}%, xunicode, xltxtra}
	\setmainfont{TeX Gyre Termes}
	\thispagestyle{empty}
	\begin{document}
	
	\addfontfeatures{Mapping=tex-text}\addfontfeatures{Ligatures=Common}IJ
	ff ffi ffl fi fk fl ij
	\end{document}

Termes is used – but *no* ffi ligature (and IJ, ij, and fk also  
don't look like ligatures). Trying to edit as Gareth described  
creates, or reveals, many problems in the font – I'm leaving it as  
amateurs playground!

We have to expect it, otherwise we would be surprised.
