The kernel has no way of doing this right now.  A suitably privileged X server
can open /dev/mem or any of the sysfs resource files and start poking
regsiters.

The reason NV and VESA work together is that the NV driver isn't a kernel mode
driver, when you switch between servers in that config the whole hardware state
is saved and restored, whereas in the i915 case, the i915 driver expects to be
in sole control of the hw once it loads.
