If one does not want normalization, the current way to specify it is
to set normalize=FALSE (but the way you tried to do it is kind of intuitive
... will think about it for the next release...)

Example

data(affybatch.example)
## using that rather than peter3
abatch.n <- expresso(affybatch.example, normalize=FALSE, bgcorrect.method="mas", pmcorrect.method="mas", summary.method="mas")


Hopin' it helps,
