In the end, I made it work and Qubes boots now on the P50. It's taken way more effort than I'd have thought though, but the cause was my lack of knowledge on how to get there; the necessary changes were in the Documentation.
In case anyone else hits a similar wall with a P50 in the near future, the missing part for me was the boot device not being recognized [1]. The detail that may not be super well explained in the documentation (probably because its too basic) is that in order to cp and mv the necessary files we need to access the LUKS partition by using the Qubes installation device and selecting the *repair* option. As I explained in a previous email, I had tried to do this before through a Lubuntu LiveCD and couldn't get access (Lubuntu said unreadable). Now that it boots and seems that at least the basics work, I will look into any hardware issues.
