 Me, too!  As we encountered similar problems during the development of the
cirrus-drivers, all I can guess is that somehting magic is going on here.

 There has been only one major redesign of the Picasso II series.  This was
when the 1 and 2 MB Version differed in not having empty sockets for
additional RAM.  Since September 1993 the design shuld not have been
changed that much, only very few details, most probably not causing the
problems (other relais for instance), have been made.

 I have exactly the same board with same specifications in my A3000.
Something we should compare as well: 

#> Version sys:Devs/Monitors/picasso file full
PicassoII-Monitor 2.51 (10.06.94)
Developed by Thomas Sontowski & Frank Mariak

#> Version libs:vilintuisup.library 
vilintuisup.library 2.9

 For me it does _not_ matter whether I boot the Amiga full blown and fully
initialized into AmigaDOS and then booting NetBSD or just starting NetBSD
(from bootblock). Does it for you?
