I think a 'good' build of sse2-i is very nice.  It seems faster in most things than the hard coded 32 bit .S stuff.

As for SHA1, possibly it is the LARGE incrementally used temp buffer that is causing the slowdown.  Since it is the compiler putting out code, possibly we could get the SHA1 intrinsic stuff running faster by using temp_var % 16 set of buffers (instead of the 'full' 80 buffers).

I have not yet.  I am still building, and testing things for all build rules, prior to trying a OMP set.
