You appear to be running kernel 6.1.0-9-powerpc #1 Debian 6.1.27-1 (2023-05-08) ppc. That may fall in the range of kernels that had an earlier issue on Wallstreet systems. In my tests, stock kernel 6.2-rc1 worked, using either "video=atyfb ..." or "video=ofonly". > "No video driver" was unchecked. So the kernel would have received "video=ofonly" from BootX. > I am experiencing graphical errors, but mach64 appears to be > working according to my Xorg.0.log.

You should find that 6.2-rc1 works for video=ofonly but 6.2-rc8 does not. The latest stock kernel should reach a text login using video=atyfb, but the screen freezes using video=ofonly (same as 6.2-rc8). Even though the screen freezes at the BootX screen, the system hasn't hung; it continues to boot and is eventually be accessible over the network (assuming you have a network configured in your rootfs). I don't think the relevant kernel developer(s) will care that atyfb (Mach64) isn't working (probably an Xorg issue), but I identified the kernel commit that seems to have caused video=ofonly to stop working on the Wallstreet. I'm still waiting for a response; I'll escalate further early next week if I don't hear anything back by then.
