Something maybe like a /dev/graph, and:
X: open /dev/graph
X: ioctl(fd, GRAPH_SET_MODE, MODE_1024_768_32)
X: CRASH!!!!!! (or kill -9) implicit exit() implicit close (dev_graph_fd)
kernel: ooh usage count on /dev/graph is 0 and we're still in gfx mode
kernel: better tell the driver to revert back to textmode
gfx driver: no problem, I know how to go MODE_1024_768_32 -> MODE_TEXT_80_25
Sounds nice doesn't it?
