At present, there is no way to install CUDA for older GPU (compute capacity 3.0) on either current or LTS julia versions. The latest supported CUDA version for cc 3.0 is 4.0, but it requires GPUCompiler that is compatible only with julia version no greater than 1.6

As explained in JuliaGPU/GPUCompiler.jl#675 (comment), this is not going to happen. I'd be happy to take PRs for additional releases of older CUDA.jl versions, but since NVIDIA doesn't support these GPUs anymore, we are not going to re-instate support for a 12 year old device.

How extensive are the necessary changes?

I don't remember by heart. Have a look at the changes in GPUCompiler, but if anything, the compathelper PRs here looked very straightforward: #2462 and #2521.
