You are right, I have tried it now without `pata` and it still works.
I also changed the module order (putting `nativedisk` to the front) and it also 
still works.
So that clarifies my remaining questions from before.

I tried this with SuperGrub2Disk, but oddly `ls (hd0)` and `ls (hd0,gpt2)` show 
the full sizes (8 TB).

I think I could -- but would it be preferable?

It seems that with `nativedisk` I can achieve a correct boot and be more 
independent of bugs in the firmware, which looks like a strong argument to me.

Thanks again!
