Bug#869817: nvidia-legacy-check_375.66-2~deb9u1 fails: + RET=20 Unsupported command "04:00.0"

[Olivier Crumeyrolle]

Package: nvidia-legacy-check
Version: 375.66-2~deb9u1
Severity: normal

Dear Maintainer,

Apparently a scripting issue prevents installation of package 
nvidia-legacy-check_375.66-2~deb9u1 when two graphics cards are present.

This hypothesis comes from the output of 
 
DEBUG_NVIDIA_LEGACY_CHECK=yes dpkg -i nvidia-legacy-check_375.66-2~deb9u1_amd64.deb

which shows  

+ RET=20 Unsupported command "04:00.0" (full line was "04:00.0 VGA compatible controller [0300]: NVIDIA Corporation G84GL [Quadro FX 570] [10de:040e] (rev a1)") received from confmodule.

as if the script tried to "execute" the second graphic card. 
Full transcript below.
Please note that this bug created significant trouble while 
dist-upgrading from jessie to stretch, as dpkg stops abruptly.

Regards,
Olivier
