Windows Media 32bit/64bit Question

I have been looking at several notebook resellers that provide custimized options. I have noticed that Sager provides Windows Media with 32bit/64bit media. Which to me means I would get both 32bit and 64bit media. Other resellers, such as DiscountLaptops, provides Windows Media with 32bit or 64bit media. Since there is no other option to provide choicing 32bit or 64bit, does this mean that the media comes with both 32bit and 64bit, but you can only install one version? Or do they pick which version depending on your configuration, such as 2GB RAM for 32bit or 4GB RAM for 64bit?

See links below for example:

I received 64bit installed but two Vista CDs (DVDs?), one with 32bit OS and the other with 64bit OS. You should be able to use either of them....after a few days I installed Vista32 w/o problems...no Key issues whatsoever.
This was one of the reasons I got the np2090 (IFL90) with Vista.
