AFAIK, enabling the write-combining cache needs to be done with PAT now. This could probably work if managed by an appropriately modified VM86 monitor, but only for real-mode games. Most DOS-extended games run without paging, which would also prevent PAT from being used. At least that’s how I imagine it would work; I’ve never looked at PAE in more detail.
