Just allocate the buffers with DosAllocMem() and set the OBJ_TILE bit. 
Actually, all memory returned by DosAllocMem() in existing versions of OS/2
is tiled whether you request it or not.  When the kernel maps the linear
address down to a virtual address for the driver stack, a temporary
selector is allocated anyway.  As a result, you don't really care about 64
KB boundaries, since these apply to the temporary selector which is
specifically concocted to avoid this problem.
