If you can boot into rescue mode / a text only mode by moving to a different console (or by using ssh to log in from another machine) install that package.
This is so for most modern cards from AMD. I hit this the other day when upgrading a machine and replacing a graphics card. If you do a text mode expert install - which I would recommend in the event of graphics card problems as a fail-safe - then at the point at which there is a prompt for additional firmware, you can insert it then. If the machine is NOT booting using UEFI, then you may be on your own - as some people have reported problems because cards expect UEFI to be present in order to hook in to UEFI to boot.
