Patch rebased against current git.

Since the original patch no longer applies to current master, and I've had an
updated patch lying around for some time, I'm posting it here so it doesn't get
lost.  It seems to still work but it's only been lightly tested.

I no longer care about this issue, since the available solutions are sufficient
for me.  I'll leave the rest to the people who do care.

Cheers.

I renamed the option to match comment #27
https://bugs.freedesktop.org/show_bug.cgi?id=23705#c27 in #27505:
DontForce96DPI.  There are Fedora 15 i386 and x86_64 rpms at:
http://koji.fedoraproject.org/koji/taskinfo?taskID=3372856 and of course
the source rpm.

I tested it and actually didn't see what I expected, so I'm not sure
what's going wrong:

$ rpm -q xorg-x11-server-Xorg                                                   
                                      
xorg-x11-server-Xorg-1.10.4-1.3.fc15.x86_64
$ grep -C2  Dont /etc/X11/xorg.conf
Section "ServerFlags"
        Option      "AIGLX" "on"
        Option      "DontForce96DPI" "on"
EndSection

$ xrandr|grep LV
LVDS connected 1366x768+0+0 (normal left inverted right x axis y axis) 293mm x 
164mm
$ xdpyinfo|grep dimens
  dimensions:    1366x768 pixels (361x203 millimeters)

I rebased Nick's original patch but I don't think I ended up with
something any different than his most recently-posted, rebased patch.

the manpage change is in a separate patch because of how Fedora's rpm
applies the patches, but that change is irrelevant for the
detection/setting of DPI.

expect to 'Option      "DontForce96DPI" "on"' to be a server flag, but
rather a Monitor option. Then again 'Option      "TargetRefreshRate"

1.9.3, maybe ever, so maybe the problem you see is not related to the
patch itself.

This patch works for me. When I set DefaultDPI to auto I get 86 DPI on
my 15" screen. Somewhat odd is that setting DefaultDPI to 123 gives 124
DPI on my 17" screen.

Would it be good to mirror what nvidia's already using?  I know their
driver called it "UseEDIDDPI", but I don't recall what Section it went
in.

Are there any progress on this patch? I will probably give my laptop to
the dev who not allowing this patch to upstream, he should burn his eyes
with it.
