[Bug 2137257] Re: Add support for Medion SPRCHRGD 14 S1 Laptop - Qualcomm Snapdragon X Elite X1E-78-100 - 32GB RAM

[James Addison]

Thanks to a friend's suggested edits to the kernel cmdline, I'm able to
access a shell prompt on my SPRCHRGD S1 Elite when booting from the
latest Ubuntu Concept resolute image (20260326).  Some stack traces /
kernel oops outputs are evident in the dmesg output -- I'll try to find
time soon to inspect and report more information about those (either
here or elsewhere depending on what they seem to relate to).

Title:
  Add support for Medion SPRCHRGD 14 S1 Laptop - Qualcomm Snapdragon X
  Elite X1E-78-100 - 32GB RAM

Status in ubuntu-concept:
  New

Bug description:
  I'm still in the situation where only `Try or Install Lenovo Ideapad
  Slim 5x` works but the actual device `Medion SPRCHRGD 14 S1` does not
  work. Note, this is the `Qualcomm Snapdragon X Elite X1E-78-100` not
  the plus version.

  I've had to add a statement in Grub to select a different device tree
  for it to boot. My `/boot/grub/grub.cfg` contains the first version
  because that seems to work whilst the second one causes it to reboot:

  ```
  devicetree /dtbs/x1p42100-lenovo-ideapad-slim5x.dtb
  ```

  
  This does NOT work:

  ```
  devicetree /dtbs/x1e80100-medion-sprchrgd-14-s1.dtb
  ```

  I've attached the `.dtb` that does not work that should work.
