Yes, you can. It often ends up as just a package like everything else, capable of being upgraded and replaced. You can even update it outside the package manager, just putting the right files in the right places -- though the package manager may never forgive you... I lost a Mandrake/Mandriva system that way, the package manager just locked up and never did anything else ever again, at all, ever, when I upgraded my own kernel. That's one reason I use gentoo, it installs kernel source, not kernel binaries, so you can do what you please with them and it won't throw a fit when I upgrade it when I want, or boot it with 3 different kernels should I want to.

URTWNFW(4)						   BSD Kernel Interfaces Manual 						URTWNFW(4)

NAME

     urtwnfw -- Firmware Module for Realtek Wireless driver

SYNOPSIS

     To compile this module into the kernel, place the following line in your kernel configuration file:

	   device urtwnfw

     This will include three firmware images inside the kernel.  If you want to pick only the firmware image for your network adapter choose one
     of the following:

	   device urtwn-rtl8192cfwT
	   device urtwn-rtl8192cfwU
	   device urtwn-rtl8188eufw

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   urtwn-rtl8192cfwT_load="YES"
	   urtwn-rtl8192cfwU_load="YES"
	   urtwn-rtl8188eufw_load="YES"

DESCRIPTION

     This module provides access to firmware sets for the Realtek RTL8188CUS, RTL8188CE-VAU, RTL8188EUS, RTL8188RU and RTL8192CU chip based USB
     WiFi adapters.  It may be statically linked into the kernel, or loaded as a module.

     For the loaded firmware to be enabled for use the license at /usr/share/doc/legal/realtek must be agreed to by adding the following line to
     loader.conf(5):

	   legal.realtek.license_ack=1
