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.
