The GPUs also have firmware blobs

OK I think we need to back up a whole bunch here and talk directly about what is wanted and going on. I am going to try an outline what I have picked up from months of this back and forth:

1. There is some sort of PowerPC workstation which is going 'to market' somewhere soon.

Alex Perez:
Wellll, it's actually been on the market for a few years. There are several variants. I've had my Talos II Lite board since January of 2019.

2. It will have high powered video cards of a PC style so will be using the same 'firmware' that would be in x86_64.

Alex Perez: 

Not will, does. Right now.

3. Those drivers expect x86_64 4k buffer sizes.

Alex Perez: 

Some do, some don't.

4. Daniel would like to have Fedora Linux as an option or the operating system on it.

5. They have been trying to work out through various tickets how to make this happen.

Please correct the items above if needed. The questions that I don't see having been asked is:

1. Is Fedora interested in being offered on this hardware?

Alex Perez: 

Err, people are already running Fedora on this exact hardware. You seem to think this is not something that's happening. You're mistaken.
