@davewill: I think that's unlikely to happen. In the perspective of I.T. department, having requirement to keep using an OS where drivers are hard to find is nightmare.

Most I.T. department buy branded PCs with service to create custom "recovery image". If the OS is not bought with the machines, these vendors will most likely decline this request (because they're likely to be unable to fetch all required drivers too). I doubt any I.T. department staffs will let this situation happen.
