I had the same problem on x86_64!

Some of the information on the following posts may be of help:
http://bbs.archlinux.org/viewtopic.php?id=63624
http://bbs.archlinux.org/viewtopic.php?id=59236

There were several related issues, I have to check again with 2.6.29.2, but with 2.6.29.1 wasnt fixed yet.

Also, something that helped a bit: I downgraded the firmware to the previous version. That made the random disconnects to became less frequent (although they didn't disappear).

I upgraded to 2.6.29.2 to see if its working better but its not.

This new firmware is really fucked, I had to downgrade as well in order to have a stable connection again.

You can find the old (and working) firmware on this out of sync mirror : ftp://mirror.rit.edu/archlinux/core/os/x86_64/iwlwifi-4965-ucode-228.57.2.23-1-x86_64.pkg.tar.gz
