I see wakeups both on my laptop (Core 2 Duo), and my desktop (AMD Phenom II), running 64-bit Linux 3.0-rc2. If you built the kernel yourself maybe you forgot to enable one of the CONFIG_* features that powertop needs? Try running powertop under strace, and see if powertop tries to open some /sys file that doesn't exist.
