Sure, but its not likely to be a simple cut-n-paste from one code base
to the other.

You won't be able to figure out what parts of lua5.2 are related to
emergency garbage collection, not easily, anyhow.
Since the patch above is already specific to your needs, it might be
easier to understand and integrate. Have you tried it? You might get
really lucky, and find it almost applies cleanly.
Also, lua 5.2 changed a lot from 5.1, particularly in the core
language and gc (ephemeron tables). Its been a while, but I recall 5.0
and 5.1 being much more similar, and 5.1 can be compiled to be
backwards compatible for almost every change.
You didn't say why upgrading wasn't an option, though its the obvious
way to get this feature. Upgrading to 5.1 should be very easy. 5.2
might be harder, depends on your situation.
