Earlier quoted context omitted.
I get the trouble for networking chipsets, but not for the video card - all x86 systems should be able to fall back to ye goode olde days of at least a text console using the old BIOS interface. A default setup of any Linux distribution should in my opinion at least automatically detect if there is something lacking for a framebuffer console or a GUI, and fall back to a plain console.
This isn't what the radeon driver does for AMD gpu's, and hasn't for years: loading the driver automatically enables the full rendering engine and disables the VESA modes, even if no firmware has been loaded. Which means that on a normal system with radeon.ko present but not the firmware files, you get a few seconds of kernel output followed by a black screen. For the systems where I don't want the firmware (servers)…
At /usr/share/X11/xorg.conf.d/10-radeon.conf:

identifier "Radeon"

Bugs may arise, maybe it could be a good idea to disable the Composite
extension too.
