xwayland issue with i965_dri.so

[Pete Wright]

hello - i've discussed this on irc but wanted to move it to email for 
wider exposure (and also providing myself with notes i can refer to later).

i am able to launch sway on my i915 intel laptop running 12-STABLE 
without any issues, and i am able to run xfce4-terminal in native 
wayland more which is great!  yet i notice this from the output from sway:

i965_dri.so does not support the 0xffffffff PCI ID.
Refusing to try glamor on llvmpipe
EGL setup failed, disabling glamor
Failed to initialize glamor, falling back to sw

i believe this is causing problems with starting Xorg apps via xwayland, 
for example chrome and firefox crash on startup.  i did some googling 
and it looks like Jan ran into this problem a while back:
http://freebsd.1045724.x6.nabble.com/Xwayland-i965-dri-so-does-not-support-the-0xffffffff-PCI-ID-td6307408.html

but other than that i haven't found any other relevant items.  i also 
tried installing patched versions of the mesa-dri ports to bring it up 
to v19, but that did not work either.

not really sure where i should start trying to pin this issue down...
