i wasn't clear enough. let me restate:

	* wine works just fine
	* you cannot load LADSPA, VST, or any other type of binary plugin that
was compiled for a 32 bit architecture into a 64 bit host.

the two issues are totally separate.

no idea. i run my dual opterons in 64 bit mode only, and build all apps
that way too.
