This patch for 2.4.0-test11-pre5 allows the use of the FM radio tuner
on BT848 cards even if the driver is not compiled as a module.

What it does: it adds the boot command line parameter bt848_radio=,
which works exactly like the radio= parameter of the bttv module.

Note: on my system, gtuner does not tune if invoked immediately after
a reboot, so I have to invoke and terminate xawtv first. This problem
appears to be unrelated to this patch, but I though I'd mention it
anyway.
