It will suffice to make a data.frame in the same order and containing the
same number of genes at fit2$genes.  If your new data.frame is called
gene.data, you just say fit2$genes <- gene.data.

You might want to look at the annaffy package and vignette for some ideas
about how to ge the information you want from the annotation package.
