What OM cameras can use a linear polarizer? Which must have a circular polarizer?

Due to the semi-silvered mirrors in the OM-{2S, 3(Ti), 4(Ti), and PC} you must use a circular polarizer with them, otherwise your exposures will be off by 2-3 stops. The OM-{1(N), 2(N), 10, G, and F) do not have a semi-silvered mirror, and can thus use linear polarizers without any problem. This problem reportedly only affects the spot metering modes of the OM-{2S, 3(Ti), 4(Ti), PC and probably OM-2000}. OTF (normal auto) exposures don’t technically need the circular polarizer, but why go to all the trouble of carrying two different polarizers and risk using the wrong one?
