DI in Models will be available in extbase version 1.4 (T3 4.6)
http://git.typo3.org/TYPO3v4/CoreProjects/MVC/extbase.git?a=commit;h=c6c01d43b8682543346f378912bea06cf5304e6e

In 1.3 you could handle it like this when you need a repositiory in a model:

$objectManager = t3lib_div::makeInstance('Tx_Extbase_Object_ObjectManager');
$this->categoryRepository =
$objectManager->get('Tx_Dedontravel_Domain_Repository_CategoryRepository');
