We have a minor problem. Richard's patch seems to refer to a
pristine xfree86-4.3.0 source. When I came to check the patch location
on a build tree that had had the Debian patches applied, I found it to
be quite different. Specifically, the line Richard wanted to change
# if defined(linux) || defined(__OpenBSD__)
# if defined(linux) && defined(__ia64__) || defined(__OpenBSD__)
Clearly, there's a Debian patch involved here. I found it at
and it goes:

... which would indicate that Richard's suggestion is already in
the current Debian package. I'd made a build log when I built the
package here, and I have

in it, so I'm sure it's in the build.
Richard, does this look likely? Are there any other places that
could stuff up the exec bit?
