I have been playing with the official Sun PS/2 adaptor brick in the
past, without any issues (can't tell you the Sun partnumber at the
moment, that device is still packed somewhere in a box).

If the OpenBSD kernel reports there is no keyboard, it is likely that
the adaptor does not correctly handle a Sun keyboard reset sequence (or
with relaxed timing). You might want to tinker in
sys/arch/sparc64/dev/comkbd_ebus.c comkbd_init() to figure out what
causes the code to consider the reset sequence did not get acknowledged
properly.
