Hi, I've noticed that the recent CURRENT got panic on some machines
if we have `device acpica' in kernel config.

I think that this is because acpi_timer device is identified twice,
so I've just made a quick fix for this so that acpi_timer_identify()
is called only once.
I hope more proper fixes would be made...
Thanks
