Hi,

I've committed several fixes for LUNA-II support:
http://mail-index.NetBSD.org/source-changes/2011/11/12/msg028833.html
and now LUNA-II can run NetBSD/luna68k, including mono X.

This LUNA-II was demonstrated on NetBSD booth at Kansai Open Source 2011
http://www.NetBSD.org/gallery/events.html#kansai-os-jp-2011
as "Of course it (1991's LUNA-II, 2001's Dreamcast, 2007's W-ZERO3 etc.)
runs NetBSD" :-)
