I haven't heard of any problems with that chipset before, and I'm rather surprised that changing the suspend_allowed() routine should make any difference for an APM suspend. But the fact is that the UHCI driver has lots of little problems, some in the area of suspend/resume as you found. None of them are going to be fixed until at least 2.6.1 or maybe even later.
