AFAICT, Gnome, GTK+ etc use "mod1" for "the other modifier"; they don't care which keysyms are bound to it. So, if you bind Meta_{L,R} to mod1 and either bind Alt_{L,R} to a different modifier or don't bind them to any modifier, Meta should work as expected in both gnome-terminal and XEmacs.

However, Xt-based apps (e.g. XTerm) understand the difference between Alt and Meta, and are normally configured accordingly. For XTerm, the altIsNotMeta, altSendsEscape, metaSendsEscape and eightBitInput resources may be relevant.
