There is NO advantage installing a 64 bit OS on a 32 bit CPU that has 
extended features to EMULATE AMD 64 bit instructions.  Other than memory 
address space and a few other things that will never be warranted on 
today's laptops.

Stick with 32 bit Fedora on all intel CPU platforms except itanic.  You 
will be fine.

Having said that, I would also propound that the opposite is true for 
AMD 64 bit CPU platforms.  You can lose up to 15 percent (from my own 
personal tests) performance by running a 32 bit made for intel 
instruction set on AMD CPUs, because it has to EMULATE 32 bit instructions.

That is one of the reasons I always cringe at benchmarks done in 32 bit 
MS Windows on multi CPU platforms comparing AMD vs intel.  There are 
soooo many things wrong with that. :)

Good luck with your new laptop.  You can check recent posts, but the 
trouble areas may include:

Wireless card -- Brodcom chipsets are just beginning to be supported.
Multi Card reader with Ricoh chipset -- just got put into upstream 
kernel, and still lacks SD support.
Display -- Fedora will probably NOT get the display right, but 
system-config-display, hardware tab, select LCD(resolution of display) 
as display type, then back to general tab to set resolution.
GNOME defaults to suspend for everything.
System/Preferences/More Preferences/Power management -- in every tab, 
change suspend to Do Nothing.  Play with suspend outside of GNOME before 
turning these back on.
