A good start might be to compare the PCI configuration registers before and after suspend. However, I suspect it's more complicated than that. Are you using the closed ATI drivers? If so, it's possible that they do something at X startup that they're not doing on resume. A good comparison might be to see if the power consumption is dramatically different over suspend/resume if you only boot to text mode - that is, never start X at all.
