Where did you see that documentation?  Here's what the Interrupt List
says:

--------B-12---------------------------------
INT 12 - BIOS - GET MEMORY SIZE
Return: AX = kilobytes of contiguous memory starting at absolute address 00000h
Note:	this call returns the contents of the word at 0040h:0013h; in PC and
	  XT, this value is set from the switches on the motherboard

I see no implications here about anything beyond 640K.

I'm not sure.  `biosmemory' is a compatibility function, so it should
report whatever is compatible.  Borland's docs clearly says that it
calls Int 12h.  Can anybody check what does Borland's version report?
