It looks like he got it from Mike Russell, though he disagrees with Russell on the details.
Regarding cofactors, the important thing (in Lane’s version of this model) about serpentinization is that it is alkaline. This would cause iron to precipitate out (as iron hydroxides and iron sulphates), and dissolve minerals such as nickel and molybdenum.
He points out nickel-doped greigite (Fe5NiS8) as a mineral with a crystal structure similar to several ancient metalloribozymes, and which he thinks was likely to have deposited on the walls of pores in the rock (serpentine?).
