Kevin,
Typically it will cause vignetting because the rings are deeper on a polarizer. This can be negated by using an oversized filter and a reducing ring. So if your lens has say a 67mm filter size, get a 67 to 82mm stepup adapter ring and use an 82mm polarizer. that will put the edge of the ring outside of the field of view and limit the vignetting.
One thing to realize however when using a polarizer with a wide angle lens is that you will most likely not have the same level of polarization across the entire image. The fact that the wide angle lens covers such a broad area, the apparent angle of the sun changes so you will see if go from light polarization on the side to heavy polarization in the middle and then low polarization on the other side depending on how you have it set. This will be very obvious when shooting a clear blue sky. You will see different densities in the blue of the sky from one side of the photo to the other. This is the primary reason that polarizers are not used with wide angle lenses.

Hi Kevin,
I have a Minolta 11-18mm and have no problems using Kenko/Hoya Pro 1 polarizer at 11m. They are the thin thin variety.
Regards,
Collin

I use a tokina 12-24 with a quantray pro "thin" polarizer which elimates vignetting. I used it with a d80 and d300 with good results.

What Phil forgot to mention (and you stumbled upon) is that an APSC sized sensor effectively has its own mechanism for reducing or preventing vignetting as it uses only a small part (about a third) of the image that would be used by 35mm film.
Of course that's itself negated or reduced when using small diameter lenses :)
