For wireless drivers the firmware is actually a binary blob on the hard
disk. The blob is loaded from the hard disk by the kernel everytime the
system boots up and is loaded into the device. So the firmware has nothing
to do with what is happening in Windows. It is like this mainly due to
some regulatory requirements for radio frequency devices.
In case of nVidia drivers, when you upgraded the kernel, the driver was
unchanged but the glue code for interfacing the driver to the kernel
(which was written to avoid opening up the drivers) had to be recompiled
to match the running kernel.
