Bug#774300: base: modprobe radeon crashes latest jessie/testing

[Vladimir K]

I can confirm this bug happens on current jessie with this hardware:

02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] 
Madison [Mobility Radeon HD 5650/5750 / 6530M/6550M]
        Subsystem: Dell Mobility Radeon HD 5650

Unfortunately I do not have free access to that machine for further diagnostic.
