Even if you can't bisect this, can you please open a bugzilla at http://bugzilla.kernel.org ? Also, if you can verify that it is really a regression since 2.6.29, please drop a note to Rafael, who tracks regressions. Plus, he knows all about suspend/resume, so maybe he can even fix it :) Maybe we quit handling fixed hardware events or GPEs for some reason.
