The problem is not really with OS/2, it lies with the AMI keyboard controller.
About a month ago I upgraded my mother-board to a 386 with an AMI BIOS set.
OS/2 1.2 was working fine on my old 286, the only change was the motherboard.
Sure enough the system failed to boot and when I tried to reinstall OS/2 1.2
I experienced exactly the same symptoms as you described (article 1106). 
Strangely, V1.1EE installed fine but blew up when I tried to run PM. I
could however get the command interpreter. 

To solve the problem I replaced the AMI keyboard controller with a generic
8042 (I think its for AWARD 286 BIOSs). OS/2 1.2 now works fine. I don't
know why the problem came up in the first place. Maybe someone out in net
land with in depth knowledge of OS/2 can give us an answer (Gord Letwin
are you out there? P.S. loved your book Inside OS/2). In the mean time I
can't recommend anyone buy a 386 system with the AMI BIOS dated Sept 1989.
If you do, make your vendor change the keyboard controller.
