akmod-fglrx doesn't rebuild the kernel at every start up, it rebuilds kmod-fglrx if one doesn't exist on the system or if the kernel is updated and a new one isn't installed.
Make sure in the motherboard BIOS settings, the onboard sound is set to "Disabled" instead of "Auto". It caused me problems with my computers. That may be the cause.
