What level of support is being guaranteed to the drivers that upstream has stopped supporting? If a bug crops up, does AlmaLinux intend to patch things in-house?

It's worth noting that the drivers are still in the mainline Linux kernel and many other distros. If they have a problem it's not just Alma vs the world to figure out the issues - it will be Alma plus the world working on the solution.
I don't think there would be any guarantees, as it is a free product. So, it would be based on things like the availability of patches upstream (kernel.org), and how many people need the fix, as well as how much effort you are contributing to the fix (be it testing, willing to replicate the issue, etc...)
If people donate hardware - probably yes.
If people with such hardware would be willing to run tests, then probably yes.
Otherwise - my guess would be no, no specific testing for such drivers would be made.
