Not sure about this ... I haven't really run Solaris on my Sparcbook.

At a guess this is concerning the recently added code (in NetBSD) which
zeros pages (in memory) when the processor is otherwise idle.  I don't know
if Solaris does the same thing, but I'm fairly sure that this wouldn't affect
the swap partition anyway.  Can you see which processes are running (ps -ef)
and see if any are accessing the disk?
