Hi,
I placed a 9600GT in a softiron 3k running fedora 25, and the nouveau
driver failed to claim the device with :
[drm] Initialized
nouveau 0000:01:00.0: NVIDIA G94 (094100a1)
nouveau 0000:01:00.0: bios: version 62.94.0d.00.04
nouveau: probe of 0000:01:00.0 failed with error -22
Which with a little bit of debugging seems to be a failure in:

By default fedora is using a 64k page kernel, switching to a mainline
4.9-rc7 kernel using the same configuration the same problem exists
(there are a couple others, mentioned briefly in the defect). Changing
the mainline kernel from 64k to 4k pages corrects the problem and a
terminal display can be seen.
The fedora defect is:
