I haven't tried this on 6.10, but I just went back and forth between 6.9 and 6.11, both with fresh installations, and on different motherboards and GPUs. Seabios GPU passthrough doesn't appear to work on 6.11; all I get is a black screen. It works perfectly fine on 6.9 on all my machines. In all these installations, I'm able to pass through GPUs just fine with OVMF. Something appears to be broken with the current implementation of Seabios. If you require any additional information, please let me know, but this should be easily replicated.
