If we add it for specific devices, aren't vendors going to assume that 
future versions of that device will also be able to rely on this 
behaviour? I'm very reluctant to add whitelisting - I suspect it makes 
more sense for us to just be compatible with Windows. My experiments 
with the T61 suggested that it was possible to get everything working 
without this, but I'll need to go back and check what the behaviour 
actually was to be sure.
