I have the same issue - downgrading the driver (with no other changes) and inserting that module seems to result in udev successfully creating /dev/dri/card0 (and working X) Also see: https://forums.gentoo.org/viewtopic-t-1041184.html Here's my emerge --info (back with the working version installed) in case there is a pattern. # emerge --info x11-drivers/nvidia-drivers Portage

with the following: USE="X acpi driver kms multilib tools uvm -gtk3 -pax_kernel -static-libs" ABI_X86="64"
I had this same problem. Turns out the nvidia-drm.ko kernel module wasn't being loaded. Tried to load it manually and it said it wasn't found even though it was right next to the other modules. Tried to insmod it and found out there were undefined symbols in it. dmesg said it wasn't finding symbols like kms_helpersoemthing. Did some digging into the kernel config and say that CONFIG_DRM_KMS_HELPER was selected by a combination of settings, one of which I had disabled (CONFIG_DRM_FBDEV_EMULATION). Enabled that and it selected DRM_KMS_HELPER, rebuilt the kernel and boom all as well. You might also have luck disabling the kms USE flag in nvidia drivers. I didn't try that.
I think actually myself and the OP were being bitten by #578014 - and this can probably be resolved as a dupe. Your comment did point me in the right direction tho - the initial version of the e-build wasn't installing nvidia-drm.ko at all, and that was the root cause.
