[BioC] moe430a and moe430av2 comparison

I was wondering if anyone knows the difference between moe430a and moe430av2
affymetrix chips.

The cdf packages that get automatically installed with them are are
moe430acdf and mouse430a2cdf respectively.  The moe430a and moe430av2 chips
have the same number of probe sets, the same probe set names and the first
65000 probe sequences (the ones I tested) are identical.  I would like to
make one expression set out of them so I can normalise all the chips
together, but I cannot do so presumably because of the different cdfs. I can
bring them in separately but if I bring them in together I get the following

Error in initialize(value, ...) : Cel file C:/Documents and
does not seem to have the correct dimensions

Does anyone know how I might be able to get around this problem?
Any suggestions would be much appreciated.
