Hi,

The missing hgu133a probe sets 

>[1] "AFFX-r2-Hs18SrRNA-3_s_at" "AFFX-r2-Hs18SrRNA-5_at"
> [3] "AFFX-r2-Hs18SrRNA-M_x_at" "AFFX-r2-Hs28SrRNA-3_at"
> [5] "AFFX-r2-Hs28SrRNA-5_at"   "AFFX-r2-Hs28SrRNA-M_at"

are all control probe sets, since the probe set IDs start with AFFX. In 
this case they appear to be ribosomal RNA probes, put on the chip to test 
whether the sample contains rRNA. I would imagine that nobody is really 
interested in the annotations for these probe sets.
Regards,
Maria.
