The splash screen appears and gets to about 30 percent, then disappears.
Before the patch, after the splash screen finishes its progress bar,

Doesn't really look like a kernel or X bug to me -- looks like a
#0 0x00007f7fe3c18eb9 in FcPatternObjectPosition () from /usr/pkg/lib/libfontconfig.so.1
#1 0x00007f7fe3c194aa in FcPatternObjectFindElt () from /usr/pkg/lib/libfontconfig.so.1
vanilla bug in fontconfig, unless FcPatternObjectPosition is working
on a graphics buffer or something.
I don't suppose you can rebuild with debug symbols and try again, can
you?
