That looks like there is no fglrx kernel module installed for the -pae kernel. Normally DKMS should build the kernel module automatically when you boot your -pae kernel. If that's not happening for some reason, that may be a bug in DKMS.
You can manually tell DKMS to build the fglrx kernel module for your -pae kernel with: sudo dkms build -m fglrx -v 8.840 -k 2.6.38-8-generic-pae sudo dkms install -m fglrx -v 8.840 -k 2.6.38-8-generic-pae Then reboot to the -pae kernel.
