I switched from 32-bit PAE Fedora 12 to 64-bit Fedora 14 on my T400.
Both could use all of the 4GB of RAM in the system.
In my experience, the 32-bit drivers are more stable. The system uses
more power now. Suspend sometimes locks the machine. Resume sometimes
leaves the screen off. It *feels* like I went back in time 4 or 5 years
to when my 600X wouldn't have sound after a suspend/resume cycle.
FWIW, Adobe does not have a release-quality 64-bit Flash player browser
plugin. Their beta version has problems playing some sound correctly on
my system. For instance, music in Pandora plays fine, but the ads have
extra bleeps and clicks, making them especially annoying. Most YouTube
videos have the beeps too.
That being said, if you have a demanding task, using 64-bit code can be
more efficient. It depends on your tasks. None of mine require the extra
bits, but I wanted to live closer to the edge. I didn't realize just how
close I would be to it, though.

Hello,
It has been a while since I've been more than a casual user of Linux,
but I
was wondering what the advantage would be of running ia32 with PAE versus
native 64-bit (x86-64 or amd64?)? Is there something which is more
efficient
or better about using it for certain tasks? The last time I worked with
Linux it was on embedded systems, and 8MB of RAM was considered "large."
