[Nouveau] Kernel 5.7.0, nouveau 1.0.15-r1, sudo lshw -C display, *-display UNCLAIMED

Hi

With Kernel 5.7.0, nouveau drivers 1.0.15-r1

sudo `lshw -C display`

will show me:

 *-display UNCLAIMED

Also `xrandr -q` will not work:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1680 x 1050, current 1680 x 1050, maximum 1680 x 1050
default connected primary 1680x1050+0+0 0mm x 0mm
   1680x1050      0.00*

So I can not start up my second monitor with this command:

xrandr --output DVI-D-1 --auto --output DP-1 --auto --left-of DVI-D-1

This used to work with Kernel 5.5.

It was "completely broken" in 5.6 and with 5.7 my first display is
back, but not my second.

I am on Gentoo Linux. Please CC for replies.

Best
