The only information you can glean from the celfile will be particular 
to the celfile itself. So you can determine that they are hgu133plus2 
chips, but I don't think you can determine the organism.

Of course you could just download the target description file and use that:

Again, probably not.

The easiest way would be to use the hgu133plus2.db package.
