You can find alternative CDF related to the paper of Dai et al. NAR 2005 at:

I have used them and in my personal experience the RefSeq remapping
works better than Entrez Genes remapping.
In our hands some qPCR validated probe sets based on Affy probesets are
lost using the Entrez Genes (EG) based custom CDFs. Furhtermore,
comparing fold changes between the same subset of genes identified using
Affy probesets or EG based probesets a generalized reduction of fold
change range was observed.
