This might be a bit late for your requirements but we have recently upgraded to Moodle 2.7 on SuSE (SLES 11 SP3). I used the unofficial/unsupported PHP 5.5 packages downloaded from http://software.opensuse.org/package/php5
Click on the SUSE SLE-11 SP 3 section and Show unstable packages. I used the devel:languages:php build rather than any of the home: ones.
If you search for php5 there is an option to show 57 sub-packages. All the PHP extensions that Moodle needs are under there.
