6950xt (rdna2) gpu not recognizable in Devuan Stable (Chimaera)

In my Chimaera system i installed a new gpu amd 6950xt . And according to the  wikipedia it's rdna2 navi21 architecture codenamed Sienna Cichlid.
My Devuan PC boots but in a smaller resolution and dmesg doesnt contain any related message. Also no gpu driver seems loaded ( lspci )

My initial setup of related install .debs :
xserver-xorg-video-amdgpu 19.1.0-2 installed but it doenst have new version backported .
firmware-amd-graphics 20210315-3 But there is a new version of the firmware backported.

So i installed :
firmware-amd-graphics 20230210-4~bpo11+1
In the firmware file it contains related firmware:
amdgpu/sienna_cichlid_ce.bin
But the issue remains.

I remember a Phoronix article on amdgpu changing the way it releases the firmware. In that case could it be that a newer version of amdgpu is also needed?

Also it seem to me strange that both versions of xserver-xorg-video-amdgpu support the same chip families.  I think there is something no rigth here. What is the relation of the driver and the firmware .debs? Can one support a family and not the other ?

Package: xserver-xorg-video-amdgpu
Version: 19.1.0-2
This package provides the 'amdgpu' driver for the AMD Radeon cards. The
following chip families should be supported: Bonaire, Hawaii, Kaveri, Kabini
Mullins, Iceland, Tonga, Carrizo, Fiji, Stoney.

Package: xserver-xorg-video-amdgpu
Version: 23.0.0-1
This package provides the 'amdgpu' driver for the AMD Radeon cards. The
following chip families should be supported: Bonaire, Hawaii, Kaveri, Kabini
Mullins, Iceland, Tonga, Carrizo, Fiji, Stoney.

Refs:

• Xorg RadeonFeature  althougth not sure if it applies to amdgpu .

• amdgpu wikipedia article

• List of AMD graphics processing units

• [Debian developer info on xserver-xorg-video-amdgpu

• Archwiki page on amdgpu . Althought archwiki is another distro sometimes you find usefull info. not in my current issue thought..

I had some trouble with a 6700XT under Chimaera, refer to https://dev1galaxy.org/viewtopic.php?id=5364, moved to Daedalus and the PC is working fine since then.
