The HP-41 PPC ROM contains a routine called IG (InteGrate) which uses a modified Romberg, similar to the HP-71's Math Pac. Its code and some commentary can be found here:

There are a few other implementations of Romberg for the HP-41 here:

There are a BUNCH of various integration programs for the HP-41 in the "Differentiation & Integration" section of this page:

Anybody? Anybody? Bueller?
