Using an Intel discrete GPU on a system that lacks ReBAR support results in somewhat lower performance, not a complete inability to use more than 256MB of VRAM.
Source? I don't know what happened for the Linux drivers, but the Windows drivers definitely booted and ran benchmarks without ReBAR when the Arc A380 launched, because there were lots of published comparisons of the performance impact on workloads that definitely didn't fit in 256MB.
I patched my old Haswell system to add an NVMe DXE so I could boot from a modern SSD. I currently have a Lets Note laptop that definitely has UEFI, but pretty much pretends to be BIOS - apparently it's possible to modify to expose UEFI features but I have yet to try...
Even though the kernel module is open-source (sort of, development still happens behind closed doors), it's still an out-of-tree module, rather than being built into the kernel, which would give you as smooth an experience as with AMD or Intel, who's GPUs literally do just work on any distro with no fuss.
It’s never gonna be a smooth experience with Linux on Macs, because of installation, but also firmware upgrades etc. there’s always some manual steps involved and nothing will change unless Apple itself starts supporting Linux natively

Whilst I have no doubt that LLMs will be useful here, I still have reservations about validation. I think experience tells us that test coverage is generally insufficient to ensure functional equivalence, and not all components are well specified.
It was all the rage towards getting 4K 120 Hz VRR on Linux before AMD came along to contribute proper HDMI 2.1 support to the kernel. There is also mention in that thread of a CableMatters adapter that could be flashed with an alternate firmware but it wasn't as stable.
Ouch, that's a tough sell. Maybe useful for AR type stuff, but I wouldn't want to go from a Quest/Index/Frame/etc to that for VR.
