osdl-aim-7 benchmark probably stresses both itlb and dtlb.
(available from osdl.org - URL is in linux-ia64 archive)

SDET is another candidate.

Note that itlb misses is a function of accesses to lots of "random"
pages in memory and having enough memory so the odds of hitting
the same page often is low. ie run thousands of jobs and the
scheduler thrash the itlb.

at least that's how I understand it.
