As mentioned earlier, support for r200 acceleration was removed from the
main branch of the OpenGL library (Mesa).  Kernel support for
modesetting remains.

I’m sorry Jonathan, the patch actually didn’t work since I had disabled 
drmradeon in the kernel so I could get a working screen. Once I re-enabled 
drmradeon and rebooted, I got the same issue.

I will let you know once I get it working.

Taking the opportunity, a question on the side, still related to this subject, 
I noticed that r200 used to show up in a previous version of OpenBSD but it is 
not in the 7.3 and reading here and there, I noticed that it is related to 
Radeon 9200, the video card in my macppc. What this «absence» imply?

Yes, the console text shows when the machine is booting, with the background in 
blue, and it goes blank precisely after the following line is shown:

[drm] *ERROR* Unable to locate a BIOS ROM

No, I didn’t agree to xenom when installing. I just hit enter for the answer 
there was [no].

The Mesa "classic" drivers, including r200_dri.so were removed from
upstream Mesa.  Mesa falls back to software rendering.  The old paths
are tried as there is a messy way to build them out of another Mesa
tree.  OpenBSD does not include drivers from the amber tree of Mesa.

Does the console text show when the machine is booting?  Did you agree
to xenodm when installing?
