Forgot to cc: this to the list initially.  Posting for completeness.
 Sequences are stored as NuIDs in the 450k package (at least for the time
being...).

> library(IlluminaHumanMethylation450k.db)
> IlluminaHumanMethylation450kNUID[['cg00000292']]
[1] "caXQ6wu1foImnrDw5U"

> library(lumi)
> id2seq( IlluminaHumanMethylation450kNUID[['cg00000292']] )
[1] "CGGCCTCAATGGTAAGTGTCCCTTGGAAGAGCGGCTGGTAATTAATGCCC"

# first probe sequence in the manifest:
> id2seq( IlluminaHumanMethylation450kNUID[['cg00035864']] ) ==
 'AGACACTAGCAGTCTTGTCCACATAGACCCTTGAATTTATCTCAAATTCG'
[1] TRUE

Granted, all this crap probably belongs in a separate .probe package...

Thanks for the question Khadeeja and for the suggestion Herve.
