I insist I can't understand why your AUCTeX runs `latex
-source-specials' for you.  Just tested on a machine with Trisquel
4.1:
--8<---------------cut here---------------start------------->8---
$ latex -v
pdfTeX 3.1415926-1.40.10-2.2 (TeX Live 2009/Debian)
[...]

$ latex --help
[...]
-synctex=NUMBER         generate SyncTeX data for previewers if nonzero
[...]
--8<---------------cut here---------------end--------------->8---

`TeX-source-correlate-method' set to `auto' let
`TeX-source-correlate-determine-method' choose the right method and
this function, unchanged since 2012-08-14 (checked with git blame),
just verify whether `latex --help' output has a `-synctex' entry or
not.  We have the same version of TeX Live, why
`TeX-source-correlate-determine-method' should return different
methods?  Are you really sure `M-:
(TeX-source-correlate-determine-method) RET' returns `source-specials'
for you, in DVI mode?

I just (re-)checked: setting `TeX-source-correlate-method' to `auto'
gives the same result as before (in my case I get `synctex' in both
DVI and PDF mode).  Anyway, in git version of the AUCTeX package the
easiest thing you can do is to leave the default value of
`TeX-source-correlate-method' unchanged:
    '((dvi . source-specials) (pdf . synctex))
This will make AUCTeX use source specials in DVI mode and SyncTeX in PDF mode.

I insist, it should have been preserved :-)

Do you customize `TeX-source-correlate-method' in your init file?  If
you leave the default value in both AUCTeX 11.87 and git version, you
should get the desired result.
