[BioC] correcting for 3' bias in highly amplified RNA samples and Affyme trix chips

Is there some way in Bioconductor to correct for 3' bias in
Highly amplified RNA samples for Affymetrix chips.

I know that Affy now has a 3' biased human chip, but I have human data that was
done with another chip and cannot be re-done. I also have mouse data and I don't
think there is a 3' biased mouse chip from Affy.

I've heard of people doing such a correction (not necessarily using BioC or R),
but I can't find any mention of it in the affy documentation or in the
Bioconductor mailing list archives.

Thanks.
