On systems with Fedora 12 or later, the kernel does not by default
alias the system device to the pcspkr.ko kernel driver any more. This
means that the pcspkr.ko driver is not loaded by default any more on
system startup.

You can check whether pcspkr.ko is loaded by running "lsmod | grep
pcspkr".

On these systems, the beep package ships a config file
/etc/modprobe.d/beep.conf with a configuration line that reintroduces
the default loading of pcspkr.ko. Due to possible side effects, you
will need to manually uncomment that line in the beep.conf file, though.

You do not need to reboot your system in order to get pcspkr.ko
loaded, though. Running "modprobe pcspkr" should do the job without a
reboot.

Caution: There appear to be some issues with access to the
/dev/console device which beep uses, possibly related to
ConsoleKit. This means that sometimes, just having pcspkr.ko loaded is
not enough for beep to actually beep. This issue is being
investigated.
