the kernel version is also embedded into the individual modules, so you'd
have to modify the kernel and every module. You might be able to do some
ugly sed trickery, but I really discourage it -- you're asking for
trouble.. and it probably won't work.

For a 2.6.22 to 2.6.23 type change though, yes you could just backup the
kernel and modules before upgrading, upgrade, rename the kernel vmlinuz
and put them back again -- though they'd then be out of pacman's control.

Why would you want to do something like this anyway?
