First, LocusLink annotation data are not in the cdf package. They are in a 
separate annotation data package. Second, we do not maintain annotation data 
package for hgu95a. But we do have the package for hgu95av2.

To get the LocusLink annotation for hgu95av2 you need to use the annotation data 
package. You may try:

>library("reposTools")
>install.packages2("hgu95av2") # add develOK = TRUE if you need the devel track
>as.list(hgu95av2LOCUSID)
