in version 1.1, except for hgu95av2 and hgu133a chips, you must 
download probe location infromation in the form of a package.

downlaod  and install the package

mgu74av2cdf

from

http://www.bioconductor.org/data/cdfenvs/cdfenvs.html

notice there is a "whats different" section 
in the vignette 

hope this helps,
rafael
