The simplest framework, I guess, is to have each plugin have an init
and an exit hook. The vga plugin's exit hook should clean up the
hardware it has messed with. Exithooks are then called whenever a
plugin is unloaded, and exiting the console should first unload all
plugins.

One could do that manually in the plugin load/unload code, but perhaps
it's also possible to let the dlopen/ld.so handle it?

Happy hacking,
