Danny I think Chris was speaking in generalities about the differences between the engines, cut a little slack. This isn't the place for a complete dissertation on racing engine design. The internet is the last place I would look to for any significant data, scientifically speaking anything on line is an anecdotal observation at best. FWIW I do believe there is a problem with the M96 motor.

I can now officially verify for everyone that Porsche has NOT fixed the RMS problem on the 997 (and, now, I should add, presumably, the new Boxster).
My car (launch 997s) now has just over 7,150 miles on it and I took it to my dealer this morning to have the oil changed. I also asked them to take a look at everything else to make sure there were no problems. In the process of doing that, the mechanic spotted slight RMS leak. The necessary parts are on order now and the dealer is going to fix it ASAP early next week. Of course, I grilled my service advisor about the situation, explaining it was unacceptable and they said they are going to take care of it. He said they frequently fixed this same problem on base 996s (as I knew) but he explained that they key was fixing it early on. He said some customers with out-of-warranty 996s or Boxters would be told about an RMS problem but would not fix it due to the price (about 10 labor hours), which only compounded problems for such owners later down the road. Based on the experiences the rest of you have had (and what you have read), it would be good to develop a consensus about how "serious" this problem really is, given the launch of a new generation of 911s by Porsche.
This, of course, raises another issue. I definitely will NOT keep this car outside of warranty.

Was just waiting for a confirmed report........
I reported some time ago that the 997 uses the Cayenne seal since they had identical part numbers. This is not true. The Cayenne seal is 948 101 212 02 and PET had the same part number for the 997 seal. PET was wrong on the 997 part number. The 997 correct part number is 999 113 490 41. The 996/Boxster part number is 999 113 490 40. Apparently the 41 part number will be the replacement for the 996/Boxster.
This is the matching but incorrect part number for the 997 in case someone thinks I dreamed it.

I doubt the type of seal will matter very much if the shaft is not running concentric in the housing.
Seals with larger radial gland dimensions realtive to saft diameter (the meat between the lip and the seal housing) can tolerate this better. The answer is to ensure the crank does not move relative to the housing.
