[BioC] simple biomaRt query

[Steffen]

Dear Galina,

Where did you get the Ensembl gene identifiers from?  It looks like they 
are not present in Ensembl and this is why getBM returns NULL.
Are you sure the identifiers are correct and have the right amount of 
0's in them?
e.g. ENSG00000008311 does return data.

Cheers,
Steffen
