You could request the OMAP arm changes be pulled up into 4.0. 4.0 is
not yet cast into stone.

Unless you were the SA syscalls explicitly (and you shouldn't have
been since we had already revised that API once without preserving
backward compatiblity which was allowed because it was in -current
and had not been included in a release branch), the removal of SA
should have been completely transparent. A newlock2 kernel and
rebuilt libpthread is all that was needed to take advantage of the
new 1:1 threading.
