Boardcom bcm2046 bluetooth problem



Hi All !

I have a Dell Studio 1535 notebook and a built-in Broadcom bcm2046
bluetooth chipset. I installed to this machine a F10, but the bluetooth
device is cannot work. I see whit lsusb, but the kernel is not detect
for this a suitable driver.
I read a solution,this device is supported the kernel, but i need
reloading the hci_usb module with a "reset=1" parameter, but this driver
is not a module  in the official f10 kernel. This driver is  linked
statical to the main kernel image.
Can i modify this parameter whitout rebuilding the kernel?
