I had a Pro that took 10 minutes to boot and then worked fine, and it turned out to be a power-related issue with the DC-in card. I replaced that, and it worked great. This machine also had problems recognizing firewire devices (it would say that a device was attached, but it would not pull it up and recognize it), and that issue also turned out to be power related and was resolved as well with the DC-in module.
 
I'd also try different RAM, if you haven't already. Also, try a different known-good AC adapter, and make sure it's 85-watt and not one of the weaker ACs they sell with non-Pro MacBooks. Actually -- I wasn't thinking -- obviously, you can rule out the AC issue by verifying that it's slow to boot when connected to the batterybattery only. Duh!
