Issues with vgacon with kernels >= 6.13

I apologize in advance if this is the wrong tree to be barking up but I'm hitting a wall on this and I'm hoping someone on this ML can point me in the right direction.  Ever since kernel 6.13 (I've not yet bisected but that may be my next step) I've been unable to get my potato system booting up via the any of the simple framebuffer consoles.  The kernel simply hangs right after loading the disk IO schedulers (which, looking at my dmesg logs from 6.12 is _just_ before the vga framebuffer is supposed to take over).  The system is definitely in the realm of antique, with a Core 2 Quad Q9650 and a pre EFI boot stage. I've tried simplefb set as the default console, I've tried vesafb, and I've tried vga=normal, all of these seem to fail just before the GPU handoff.

The major change I do see around 6.13 was a change to support the DRM friendly panic message and I'm tempted to maybe think that's where the regression lives. I also realize I may be one of maybe 6 people affected by this by keeping this system limping along, but I do use it regularly to test SIMD related performance, as it's the last CPU family in Intel's line that actually has the unaligned load penalty.

This is the last kernel message I see prior to boot (hopefully LKML doesn't flag me for adding a URL, but I figured attaching an image would be worse):

Does anyone know of any major changes that might have caused this and anything I should try? My previous configuration is actually to use uvesafb, of which has been failing due to v86d being missing from my distribution for some time now, but it would gracefully fallback. I have an nvidia GPU in this system so the nicer fb options aren't really a thing.  The builtin nvidia modeset is a thing and it does work but that doesn't happen until much later in the boot process. For all intents and purposes, I'm relying on VBE right until that module is loaded, but it hangs much much earlier than that.
