When I try to run that game, I get "Failed to load libGL: libGL.so.1:
failed to map segment from shared object" with or without your
patchset.

I also tried adding 100, 500, and 1000 MB to pvmi->VirtualSize and
pvmi->PeakVirtualSize and that didn't help either.

So, although this patchset is interesting, I'm not convinced that it's
the right solution. There must be something else going on.
