[BioC] getGEO without platform?

Hi all,

I was wondering if there's a way to use getGEO to end up with an 
ExpressionSet without platform annotation. Why? I have lots of GEO 
entries from which I want to quickly extract the exprs values, and I 
don't care about the annotation (and I can always download it later on).

I've been trying:

geo <- getGEO("GSE11899", GSEMatrix=TRUE, AnnotGPL=FALSE)

But for "GSE" ids it seems to ignore the AnnotGPL flag and goes ahead to 
download 38.1 Mb (in this case) of text annotation!

Many thanks,
