No, that's not usual. I use ipw2200 on my laptop, and typically spend 20-30% of time in C3. For me, the biggest wakeup culprits are in userspace - hald, firefox, and X.

I you look at this powertop page[1] you will see it says

Xorg shows up high on the hall-of-shame list
Xorg generally does work on behalf of other programs, so if Xorg shows up high on the list, there are other programs that make it do work on your system. In our experiments with an "ultra idle" Linux graphical desktop, Xorg is indeed not showing any activity.

So it is not X that is the problem - it is a proggy that is causing X to wake up that needs a slapping.
