--- Comment #40 from Andrey Borzenkov <arvidjaar at gmail.com> ---
Using current kernel.org git as of dd36d7393d6310b0c1adefb22fba79c3cf8a577c and
adding 0x118 to select 0x117 driver I get

/dev/dri nodes are correctly created for a second card. Unfortunately attempt
to actually run something on secondary GPU results in

[   184.755] (II) [drm] nouveau interface version: 1.3.0
[   184.755] (EE) Unknown chipset: NV118

While running up to date kernel is easy, getting up to date Xorg is probably
more challenging (I'm writing this on Ubuntu 14.04). But kernel side looks
promising. Please let me know if you need any additional logs from nouveau or
nVidia driver.
