[BioC] Dealing with artifacts on Affy chips.

Are there any common methods that deal with artifacts that appear on
affymetrix arrays? Some of our HGU133A arrays have 'comet-like' high intensity
regions. I've isolated the probes contained within these artifacts and was
wondering if a 'mask file' could be created in R and these chips re-integrated
back into the original dataset? I'd like to include these chips in functions
such as rma and hclust etc.
