Comment # 1 on bug 1234914 from Stefan Dirsch

kernel-firmware-nvidia-gspx-G06-cuda=565.57.01 is only needed on SLES for
historic reasons. Actually it became a fake/meta package. You don't need it on
TW.

$ rpm --requires -qp
nvidia-open-driver-G06-signed-cuda-kmp-default-565.57.01_k6.12.6_1-173.2.x86_64.rpm
| grep -v ksym | grep gsp
(kernel-firmware-nvidia-gspx-G06 = 565.57.01 if nvidia-compute-utils-G06 =
565.57.01)

So once you install nvidia-compute-utils-G06 = 565.57.01 the appropriate
kernel-firmware package gets installed. Both are in NVIDIA's CUDA repo.

Not sure why this doesn't work on your TW installation. Maybe it helps to
uninstall old nvidia-open-driver-G06-signed-cuda-kmp-default and
kernel-firmware-nvidia-gspx-G06-cuda packages.
