Some more datapoints : I managed to recover the card. I had to unplugged it and then boot the laptop. Switch off, re-plug, reboot and it is there.
I attach lspci -vvv with the card now present. As I will get some spare time in the next days I will try to reproduce this one. Happy Christmas Ubuntu fellows !
