Please excuse my ignorance in such matters but would it be possible to 
use a RISC-V or FPGA chip as an interim eGPU until such time that a more 
specialised chip can be developed and released?

I appreciate that RISC-V/FPGA chips are not likely to be well-suited to the task
of GPU processing but perhaps they would be better than no GPU at all.  

Once a specialised libre GPU has been developed, the RISC-V / FPGA chips 
could be repurposed as a CPU for other projects/computers/laptops/etc. and, 
hence, ensuring that they don't go to waste.
