I'd say: write a wrapper in gdi which
	1/ sets DS to the GDI_HeapSel value
	2/ calls LocalAlloc16 (for instance) (the call has to be a 16 bit
call),
	   so you need the relay to be generated for this 16 bit call
	3/ restores old DS value (before 1)

this sounds hacky, but it was a standard way of using the LocalXXX on
several
64k buckets at the same time

you may also create a new type of 32 => 16 relay stub, which sets DS to
a
passed value... (that'd be IMO the cleanest way...)
