Those drivers are for obsolete hardware that the old maintainer didn't care (or not have the hardware anymore), and that no other developer could find any hardware to buy. They probably have no practical usage today, and people with such old hardware could probably keep using an older version - of the kernel. Those drivers will be moved to staging on 2.6.37 and, if nobody - care enough to port and test them with V4L2 API, they'll be removed on 2.6.38. + of the kernel.
