PS/2 keyboard mapping on HP/UX 11i

Hello guys,

I've noticed that some PS/2 keyboards (mostly those which has WinKeys, but also several true old keyboard) on B160/B180 has a strange key mappings; so, instead [left control] [Alt] (or some winkey even?) should be pressed. At least in 11.11's X.
Is there a way to remap it?

I have a PS2_US mapping selected during installation (and I've verified that by re-running keyboard setup program). During the installation I used some old keyboard which worked fine, but now I do not have access to it.
