Thanks for your patches. That could finally solve the missing
co-installability of the kernel modules.

Switching between current and legacy is done by reconfiguring the nvidia
alternative (/usr/lib/nvidia/nvidia) - can't that be used by the module
load script to select the "right" module? And "right" is here not what
fits the hardware best ... but what was configured.

The initial selection of the right driver (and setting the nvidia and
glx alternatives) is a different problem to be solved by the live system
boot process ... nvidia-detect should be able help with this, it looks
at PCI IDs and checks the lists. If you need machine readable output -
patches are welcome.

Needs to be done for -source, too.

If I have a card requiring legacy-173xx - do
  modprobe nvidia
and
  rmmod nvidia
still work afterwards?

Anyway, this looks like stuff for wheezy+1.
