The kernel doesn't have a stable API for drivers, so not developing
against an ancient kernel [1] reduces the amount of work required for
porting it to the latest kernel when submitting it for inclusion.
But development kernels (including -rc) kernels are more likely to have
bugs you might run into.
And doing development with a development kernel you are regularly
updating to the latest one can easily be a bad idea since this would be
two moving targets increasing making it harder to trace problems.
If you are e.g. developing one more standard network or ALSA driver
2.6.19.2 sounds like a good choice to work with.
Things might be different if you are developing a driver in an area like
e.g. SATA that is heavily developed and might have changes affecting
your driver in the latest development kernels.
Whether you use a git tree or tarballs from kernel.org for getting the
kernel shouldn't make any difference. Like with all software development
it does make sense to maintain the code you develop in some version
control system, but whether that's git, CVS, Subversion or anything else
doesn't matter as long as you can work with it.
