I have not had much experience with chipseal (not that I'm complaining

) but I think you can make modifications to make it less unpleasant, specifically with your tires. Someone please correct me if I'm wrong, but I think wider tires will help, e.g., 25 or 28 mm instead of 23 for a road bike. Also lower air pressure should help. Just make sure your frame can work with the wider tire; someone at the LBS told me my Madone can use a 25 but not a 28. If you have a touring bike, you can probably go even wider.
