I'm not sure which Intel manuals you're looking at already. A quick
bit of searching finds some that might be useful.
The Intel C/C++ compiler manual at least lists the available
intrinsics and gives some very brief introductory information. Search
for "intrinsics" in the index:

Note: the compiler manual references an SSE2 "external architecture
specification" that does not seem to exist.
Here's a short introductory manual on using SSE and SSE2 (with both
intrinsics and inline assembly):

There's some specific examples here:

A short magazine article:

Some online tutorials with examples; the first one may require some
sort of registration process:

An introduction to SSE programming:

And of course there's the instruction set reference manuals, which I
think is where they've put the SSE stuff these days:
