[BioC] Problem with limma2biomaRt and MBNI custom CDF

Hello,

I get the following biomaRt error when trying to use the limma2biomaRt function in conjunction with a limma fit2 object created from a MBNI custom CDF.  I thought I was faithfully following the "Annotating data with affycoretools and biomaRt" vignette.  

THE ERROR

> limma2biomaRt(eset.mbni, fit2.mbni, design.mbni, cont.matrix.mbni, species = "hsapiens",
+ pfilt = 0.05, interactive = FALSE)

Error: ' entrezgene 'is not an available annotation source for this biomaRt or this species.
Available choices are listed below:
                              name                              description
1                     affy_hc_g110                      Affy hc g 110 ID(s)
2                    affy_hg_focus                      Affy hg focus ID(s)
3              affy_hg_u133_plus_2                Affy hg u133 plus 2 ID(s)

...cutoff for brevity.

I'm fairly sure the gene IDs in fit2.mbni are indeed entrezgene IDs:  

> fit2.mbni$genes[1:5,]
[1] "1_at"     "10_at"    "100_at"   "1000_at"  "10000_at"
