Hi Kaj,

Currently you cannot create a chip level annotation package without a 
corresponding .db0 package. You can however create an organism level 
package using makeOrgPackageFromNCBI() in the AnnotationForge package, 
and then getting the annotation file from Agilent. You can then use the 
Entrez Gene IDs from the annotation file to then use select() to get 
whatever annotation you might want.

If you are using limma, you can put the annotation data in the genes 
slot of the MArrayLM object, and those data will appear in your
