You don't need the modules and the GUI to downgrade the kernel package
if the updated kernel should be broken.

1. Boot the old kernel
2. Login on the text console
3. pacman
-U /var/cache/pacman/pkg/kernel26-<lastworkingversion>-<arch>.pkg.tar.xz
4. reboot

Old kernel and its modules are back.

But before you do this, you should write down or copy the necessary
error messages and details to file a bug report about the kernel issue.
