[BioC] Genbank accession annotation?

What package would I need to transform Genbank accession numbers into
gene symbols or entrez gene ids?  e.g.If I search "R28020" on NCBI, it tells
me that "This EST is one of 1366 sequences matched to RAB2A: RAB2A,
member RAS oncogene family. "

Is there a metadata package that has this kind of information in it? I have a
couple hundred such identifiers that I need to map to genes.  I'd like to
be able to run

getSYMBOL("R28020", "some_annotation_package")

and get a useful result.  Any ideas?
