what would be creating problems for kernel modules compiled against the

A clean install won't help you. There's a bug in anaconda that makes it
choose the wrong arch for the kernel:

There's a lot of bad advice in there, though. I really wouldn't suggest
removing the kernel that you have installed -- it'll confuse grubby, at
least, and possibly render the system unbootable if you're not thorough.
Instead, download the i686 kernel and use:
rpm -Uvh --replacepkgs --replacefiles <kernel.i686.rpm>
Reboot, and your wifi should start working.
