using gnu as for 16 bit code?

Ok, from everything I read, as does not generate 16 bit code, so I wrote and assembled my bootloader with nasm. This is no big deal, but I will develop the rest of my OS with gnu as to interface gcc, so for the sake of consistency, Id rather have all my code written in ATT syntax rather than have the bootloader in intel and the rest in ATT. Does anyone know how to do this?

Please see the gas manual.

As far as I know, GAS can emit 16 bit code as normal, but it's not necessarily 286-compatible code.

That's just a case of picking the right instructions, IIRC.
