ABI Mismatch causing server crash on startx

[B0BAA]

Describe your issue

OS: Gentoo Linux
Kernel: 6.18.7-gentoo-dist
nvidia-drivers-590.48.01-r1
x11-base/xlibre-server-25.1.0
x11-base/xlibre-drivers-25.0.1

when trying to startx facing an error,
This server has a video driver of 28.0 that is not supported by this NVIDIA driver. Please check http://www.nvidia.com/ for driver updates or downgrade to an X server with a supported driver ABI

This happened after upgrading to the new bumped drivers and I've tried to ignoreabi in /etc/X11/xorg.conf which also does not seem to work .

Steps to reproduce

1. emerge --sync xlibre
2. emerge -avuDN @world (I know this is probably not the correct way but I was lazy)
3. Reboot and Startx

What did you expect?

No response

Additional Information

$ startx

Note: This error was not happening before the latest xlibre drivers were pushed and I was able to use xlibre with no issues.

(EE) modeset(1): drmSetMaster failed: Permission denied

Same as #70 , i.e. modeset exploding where another driver has already been loaded for the device, i.e. another casualty of the ongoing mess around driver slot claiming -- /xserver/issues/1505, xserver/issues/1565, xserver/pull/1564, xserver/pull/1650 ...

This was all raised quite some time ago, so I for one am just going to mask 25.1.x until it is sorted out.
