Yes, that won't work; HuGene-1_1-st-v1 and HuGene-1_0-st-v1 are
completely different chip types with incompatible CDFs.

It appears that Affymetrix does not provide a CDF for the
HuGene-1_1-st-v1 chip type.  However, they do provide
HuGene-1_1-st-v1.r4.PGF and HuGene-1_1-st-v1.r4.CLF files (part of
their 'HuGene-1_1-st-v1_strip_libraryfile.zip' library file available
on their website).  It should be possible to create a CDF from these
file.  At the moment, there is not such support built into
aroma.affymetrix, but you could use the Perl scripts provided by
Elizabeth Purdom and Mark Robinson, see How To page 'Create a CDF file
from scratch (or from CLF and PGF files)'
[http://aroma-project.org/node/40].

Hope this helps

When reporting problems on aroma.affymetrix, make sure 1) to run the latest 
version of the package, 2) to report the output of sessionInfo() and 
traceback(), and 3) to post a complete code example.
