DDQOTD (Dumb Distro Question of the Day) Does Fedora 10 install as a 64 bit OS when it senses 64 bit hardware?

[Alex Hewitt]

I have a copy of Fedora 10 that came inside a Linux Format magazine. I 
installed it on a new system with 8 gb of RAM and a quad core AMD CPU. 
When I issue the free command I see all 8 gb of RAM. Does that mean that 
the distro installed itself as a 64 bit version? If so, is there an easy 
way to tell? uname -a gives:

"Linux hostname.localdomain 2.6.27.5.117.fc10.i686.PAE #1 SMP Tue Nov 18 
12:08:10 EST 2008 i686 athlon i386 GNU/Linux"
