I've also written quite a few hosted and non-hosted device drivers (in C). None of them have any global variables.
The point is to be able to properly model, understand and if necessary implement *entire systems* without using "global variables" (allegedly). You can always define sub-system boundaries in such a way that you can claim that this/that or the other sub-system, device driver or whatever does not use "global variables" if you put the global variables somewhere else and pass a reference to the sub-system concerned. We could play that game with Data.Unique, for example.
