There is also a problem in OS/2 16-bit with the 15-16Mb portion, seems that the OS/2 pretends to put there something (the BIOS, surely, as this version was able of loading a disk-based protected mode BIOS' based ROM and had one for AT and one for PS/2 machines, the ABIOS was called, see old OS/2 books) in RAM and maybe is making that portion of RAM to appear at that location, and if that portion isn't empty (has real memory) the system hangs.

Try to boot it with less than 64Mb (48Mb for example).

OS/2 hangs when 64Mb are informed in the standard way they seems to check that in some strange way.

No matter it is 4.0, 4.5, eCS or whatever.

Could this be because of OS/2 memory handling differs from many others in this way:

Memory "filling" is started from "top" to "bottom" ? (highest address first)
