It's the same problem for either side. I have not seen a specific TSB for drivers seat. I had the problem in my 05 STS drivers seat and took the passenger seat TSB to the dealer and thry had no trouble fixing it while I waited.
What is the document number for the driver's seat? Thanks.
This is what I found regarding the sqeaking driver's seat. It's a different one than what you posted. I'm pretty sure this is the one to cover the problem with the driver's seat. I don't have a document number.
TSB Number : 06-08-50-010 Issued Sept 06 Description: Interior - Front Seat Cushion Pops/Creaks/Moves
