Just to throw in my thoughts: Of course it's better to avoid zeroing pages than to seek for a fast zeroing routine. I'm wondering if for the 486+ there's something faster than mov eax,0 rep stosd. For the 8086 a fully unrolled page clear like rept 2048 mov [bx],ax inc ax endm would have been faster (I think stosw wasn't too fast). Having aunrolled clearer for a full page you could computer the entry point even for different sizes, but is it really woth it?
