Has anyone had a look at this? Upgraded to latest mesa today and the problem is
still there. Even omlsync in mesa/demos is broken. :/

I did some extra output from omlsync.c:

glXGetSyncValuesOML(disp, winGL, &ust, &msc, &sbc);
fprintf(stderr, "ust: %lld, msc: %lld, sbc: %lld\n", (long long)ust, (long
long)msc, (long long)sbc);

Result is this:

ust: 0, msc: 0, sbc: 8912
ust: 0, msc: 0, sbc: 8913
ust: 0, msc: 0, sbc: 8914
ust: 0, msc: 0, sbc: 8915
ust: 0, msc: 0, sbc: 8916
ust: 0, msc: 0, sbc: 8917
ust: 0, msc: 0, sbc: 8918

Doesn't seem correct to me that neither ust nor msc are incrementing.
