Here's a slice from the i386 INSTALL notes:

     NetBSD System Requirements and Supported Devices:
     ------ ------ ------------ --- --------- -------

     NetBSD/i386 1.0 runs on ISA (AT-Bus), EISA, PCI, and VL-bus systems
     with 386-family processors, with or without math coprocessors.  It
     does NOT support MCA systems, such as some IBM PS/2 systems. 

As of this time, no.. it doesn't support PS/2 due to the MCA ("Micro
Channel bus").

If memory serves me right, IBM wanted the developer to sign a NDA
("Non Disclosure Agreement") for developers if they wanted specs for
MCA.  Since all source code for NetBSD drivers are totally free, it
would be a violation of that NDA.

(The i386 team might want to comment on this, I'm not totally sure
since I never had a need to write for PS/2's or MCA).

btw:  OS/2 is the operating system, PS/2 is the model of the computer.
