They don't have any alignment restrictions per se, but like aasimars trend to good and tieflings tend to evil, it's my understanding that earth and water trend to law and fire and air trend to chaos.
Slightly off-topic, but not so sure about this? I mean, while the western understanding of the four elements presents earth and water as stable (ish, in water's case) and fire and air as unpredictable, other cultures interpreted them differently. It is also considered customary for a planetouched to inherit the alignment traits of their planar progenitor, which in the case of fire genasi might be the Lawful Evil efreet. Water genasi have the chaotic neutral marids (the sea is a harsh mistress), earthies have Dao (NE - IIRC one of my favourite Earth Genasi PCs on Amia was a bit this way) and while air genasi have the djinn (chaotic good), one could I dunno theoretically inherit the mindset of the lawful Wind Dukes of Aaqa? Bit of a long shot really.
All of this is fairly moot as there are no alignment restrictions on any of them, and Races of Faerun graced all four classes with the beautifully generic Favoured Class: Fighter. I find it helps to consider these angles at least, helps for making more diverse characters.
