[BioC] mapping kegg gene ids to probeset

[Dr.Mayhaus Manuel]

Hi,

Does anybody know how to obtain KEGG gene-ids for a list of affymetrix 
probesets.
I manage to retrieve probesets or entrez-gene-ids for a given KEGG 
pathway, but I need to know which probeset represent the individual 
KEGG gene (eg.: the gene "mmu:108960" is part of pathway "mmu04210", 
but what is the underlying entrez gene or probeset...)
Thanks in advance for any help
