The following code should get you the mappings between map and probe ids. You 
may then save the mappings using saveMat.

>temp <- eapply(hgu133aMAP, paste, sep = "", collapse = ";")
>temp <- cbind(names(temp), unlist(temp))
>temp <- AnnBuilder:::getReverseMapping(temp)
>map2Probe <- cbind(names(temp), unlist(temp))
