My nice-but-cumbersome lapdog decided some time ago that being asked to suspend is insulting or something, and now goes catatonic instead: the suspend works fine, but absolutelly nothing, ever, wakes it up again.

"Roses are red and my SO-DIMMs still hot,
you asked me to sleep but I'll let you rot."

A lot of debugging (and swearing) later, I now know that the culprit (at least for kernel 2.6.35.14) is the module lpc_sch, which isn't needed for normal operations anyway. blam! Bye-bye, module.
