Disclaimer: I didn't do any Ruby driver yet. Atyfb is in my (long) todo bucket.

I _think_ you can nicely encapsulate a 2.5 style driver using a 2.4
compatibility layer. Just add some stubs that take care of get_{var,fix}() and
of the extra con argument.

Since these stubs have to be the same for each driver, what we need is some
include file that provides the compatibility layer, and some additional #ifdefs
I guess, or clever macros.

Is this correct, James?
