Those numbers are NOT written to VGA by the x86, that's what the BMC does (presumably based on port 80 writes, but that's irrelevant). As I said, I don't give a flying f*** about that stuff. The BMC can do whatever the hell it wants.
I want the BIOS and early boot, running on the x86, to write its output where it's supposed to, which is not the VGA, since that is "disabled".

@brouhaha@mastodon.social with the noted caveat that you cannot redirect the output before the BIOS is actually giving any output (those are just a fancy BMC version of the onboard Q display), it could be that depending the GPU you have, you might have to activate CSM (Compatibility Support Module), so that the BIOS can actually use your GPU; not all GPUs have proper UEFI support and especially older dedicated graphics cards as such will not init until the OS actually does that.
