If the driver supports changing modes, and there is an app which
can make an ioctl() call, then the change can be made. The kernel
probably won't notice the change, and it may get confused if,
while the mode is selected, some other app (like the window manager)
tries to make a call to display something. OTOH, my version (with
X and GNOME) seems to switch to 80x25 very easily when I press
CTRL-ALT-F1 through CTRL-ALT-F6, so the kernel must support
_something_ along those lines.
I'm not an expert in what the kernel does to manage the display.
