X is consuming ~100 GiB of RAM(!)

One possible problem with using modesetting in 1.15.2 is that it was
recent, and sometimes regarded as experimental.  Nowadays it is
built as part of the xorg-server (provided the dependencies are
present), but I've no idea what SuSe did in that old version -
generally they seem to make it hard for people not using their
distros to find how they built the source.  So maybe using
modesetting will fail - I hope not, because on one of my previous
cheap machines it improved the CPU usage significantly when running
X, so I now regard the modesetting driver as well worth having.
