Have a look at the Linux kernel source, in drivers/sound. You could dig some in
the ALSA (www.alsa-project.org) drivers as well, but the modularized design
might make it harder finding your ways around at first. There are some
documents and links on the ALSA site as well, and I think most of the
supported chipsets are documented there.
For some ideas on how to port to RTL, you can have a look at the downloads page
on the Audiality site, but beware - it's for an old RTL version, and I haven't
touched it for ages... The principles are the same (that is, the same as for
normal kernel drivers), but the API has changed a bit. (BTW, the included driver
is for the AudioPCI chipset - a 2 in + 4 out set without a hardware
synthesizer.)
