if this is a recent 2.6.25 kernel, this is a known bug (my own PC shows it);
Venki fixed this on Monday so hopefully the fix will make it into 2.6.25

those aren't actual wakups, they're the mechanism for which real wakeups are done.
PowerTOP deliberately doesn't show these because
1) they're not real wakeups
2) because of that, showing them anyway would only be confusing for no reason

If you have actual timer interrupts that happen, PowerTOP does report those separately.
(as "Extra timer interrupt".. there've been a lot of questions about these before)
