Linux on PA-RISC also has an upward-growing stack (AFAIK, it's the only architecture Linux has ever had an upward-growing stack on; it's certainly the only currently-supported one).
Both this and parent comment about PA-RISC are very interesting.
As noted, stack growing up doesn't prevent all stack overflows, but it makes it less trivially easy to overwrite a return address. Bounded strings also made it less trivially easy to create string buffer overflows.
