Absolutely. Plus the old licensing scheme has not been enforced for 20 years. Do you see ATI paying the license when they sell (sold) Radeon PCI cards which had Amiga drivers? Nope
Sell your new Amiga gfx card product with a full hardware reference manual, but no driver. Include enough information for anyone to develop a driver.
Then let "the community" develop a driver for it
Job done.
