I, too, just upgraded a Tivo HD with the same drive (the drive had a "born on" date of March 2010) and have had no soft reboot problems, even after soft rebooting several times. (In fact, I do it a couple times a week just to see what happens). Wait. That sounded wierd. Anyway, I have not done any disabling of Intellipark. It has been working fine for almost two weeks. Not sure if the other shoe is going to drop on me here or what, but so far so good.
