NetBSD and OpenBSD handle input devices (keyboard and mouse, but it has 
some room to handle tablets or touchscreens too) hotplug in their wscons 
driver. This is similar to what recent Linux does.

Wsdisplay has no real support for hot-plugable graphics cards, but some 
work is beeing done in this area to support compact-flash VGA cards that 
are available for PDAs.

For the X server it's important to keep its own abstract model, 
independant of specific systems interfaces, of all these hardware 
interface operations. The model can be inspired by an existing 
implementation in a specific OS (ie Linux) but it needs to leave room 
for other implementations.

To be this model, HAL would need to support all systems on which X can run.
