Sorry I can't give you any HOWTO - I didn't make notes and currently
don't have the Intel compiler installed.

But what you plan to do is certainly possible. A few months ago I
successfully recompiled Python (not just the extensions, the Python
core too) with Intel's compiler on Linux.

As long as you remember to expose your module initialization function
with DL_EXPORT, everything should be fine.
