I am not sure if it is a NetBSD specific, the tweaks consisted of
changing some LWP thread functions from (void)(...) to (int)(...) and
cast the LWP argument to a (char *) when creating the LWP thread.

were some LWP related changes that went in recently.  I will shoot you
the patches tonight.

Ah yes, I forgot about an unaligned access.

Yes, will give that a go tonight for you.
