This is all suggesting to me a fairly serious setup problem, but not
necessarily a problem with Myth.

You are correct - there is no mythfrontend log file. That would be on
your server. My mistake. You still might want to look through the tail
of that file but I doubt anything about this will be there.

As I said earlier, you should simply remove the freetype line from the
fonts section of your xorg.conf file. It's not an issue though.
PRobably the same for the type1 font, assuming it's a font. Xorg isn't
finding those fonts which jsut means it cannot use them. That's not
going to cause a crash in Myth though.

I'm not understanding why your system isn't finding the right video
driver. It appears hal wants you to run the i915 driver. Is the i915
driver in memory? (lsmod|grep i915)

Is it on your system? On the 32-bit machine they are in /usr/lib/dri.
Your Xorg.0.log file says they aren't there. Why not?

dragonfly ~ # ls -la /usr/lib/dri/
total 8824
drwxr-xr-x   2 root root    4096 2009-04-12 08:37 .

dragonfly ~ #

If they really aren't there then you need to build them. They are
provided byxf86-video-intel.  I don't have them on this AMD64 machine
but note that if I wanted to add them then they drag in XvMC which I
am suspecting is causing the segfault crash on my wife's 32-bit Intel
based machine:

lightning mythtv # emerge -pv1 xf86-video-intel

These are the packages that would be merged, in order:

I am curious as to whether this matters. xvmc is one of the rendering
technologies and is pretty much default with Myth. On my wife's
machine neither implementation is selected. Possibly that's part of
the problem on her machine. I'll have to play with that a bit:

dragonfly ~ # eselect xvmc list
Available XvMC implementations ( * is current ):
  [1]    xorg-x11
  [2]   intel
dragonfly ~ #

I don't know what other clues to give you. I'm going back to xorg-1.3
as we speak to see if I can get her machine working again. I'll let
you know how it goes.
