If the driver and FW update will be within the same kernel release then IMHO there should be no compatibility problem between those two components, right? This way kernel users willing to stick to old FW can stay on older kernel version while others can update and receive all the latest FW functionality that was developed and enabled.
I am not comfortable with precluding a kernel update because of a single firmware file. There are all sort of reasons for updating a kernel, security, sideband attacks and Android CDD compatibility being the most obvious ones.
Right, this is the whole ABI guarantee thing - we'd need an incredibly strong reason to require a change in firmware for upgrade of existing systems.
