You are either not reading the answer right or we mis understood your question.
YES you can use the upgrade version of 64 bit W7 when you have 32 bit Vista installed
BUT it will not upgrade 32bit Vista ....It will make a NEW installation and place your 32 bit Vista
in a seperate folder called Windows .Old if you install it to the same partition.
is that more clear???
The term upgrade is usually used in reference to Over Writing an old installation with the new.
This is not going to happen ..
And yes you need way more space. 20 gb covers the installation and then there will be the never
ending updates....that will require more space.
You might consider installing another HD and using all of the old one for those programs ,personal stuff etc
while using the new one for W7...maybe even partitioning the new one into 2 with the 2nd partition
for all of those 64bit programs that you will no doubt be purchasing to support that 64bit OS.

Well I dont know where it is all you guys get your information. Microsoft themselves have said its possible.
Here are some other articles from people confirming that.
