This is something that should be taken to Lenovo Technical Support. I
have two laptops and neither of them have problems hibernating with
Windows 7; one is 32-bit and one is 64-bit - An Asus and a Dell with no
drive letter assigned to the System Reserved partition on either of them.

Thanks Bobby, but there's no way Lenovo is going to be able to help me
with this. It's a real killer of a problem, and those guys generally
have a book they use to troubleshoot stuff like this. The solution to
this one ain't in no book...
