[BioC] Affymetrix Human Gene 1.0 ST Array

I would like to analyze Hume Gene 1.0 ST Arrays using BioC. I am
interested in differential expression at probeset and at gene level.
Searching the list archives reveals, that "makecdfenv and
makePlatformDesign make the assumption that there is a one-to-one
mapping of probe ==> probeset", which is not true for the Human Gene 1.0
Anyway, I found some interesting packages:
- exonmap: Looks promising, but there are no cdf files for the Gene 1.0
Chip on the related website (just for the Exon 1.0)
- xps: This seems to be a completely new infrastructure for affymetrix
chips, which is capable of reading the Gene 1.0 Chip.
- aroma.affymetrix: This is not a BioC package. (Why not?)
Have I overseen a package? Can someone point me to further information
regarding BioC and the Human Gene Chip? I am not sure where to start and
appreciate any comments and experiences of other users.
PS: Is there any work going on the integration the Human / Exon Chip in
the affy packages? Or are these Chips too different from the
conventional 3' Chips.
