4GB+ on 32-bit Vista?

I was under the impression that 4GB of mem was a limitation of a 32-bit
environment. Over at winsupersite.com, the 32-bit version of Ultimate is
16GB+ (or motherboard max). How much mem can the 32-bit version of vista
ultimate hold?
 
Any 32-bit version of Windows can hold up to 4GB, and 64-bit can hold up to
16GB (I think).

This is correct. 4GB is the maximum amount of memory that a 32bit operating
system can utilise.

That 16 GB is most likely the hard drive space taken up by the install of
Vista, and not the RAM.

4GB.

No, Vista does not use that amount of hard disk space, the required amount
is 11.5 GBs for the install, the actual amount used is 8 GBs.

That's not quite true Jane:

PAE permits access beyond - on 32 bit server versions of windows anyway:

http://www.microsoft.com/whdc/system/platform/server/PAE/pae_os.mspx
and
http://www.microsoft.com/whdc/system/platform/server/PAE/PAEdrv.mspx

We use 8GB of physical RAM on Win2K Advanced Server at work for example, and
some applications, like MS SQL Server, can utilize this as they are AWE aware.

However, there are performance/compatibility issues when compared to 64 bit
native O/S.
