To rephrase your question: you want to know how to upgrade the UART driver when you upgrade the kernel from 2.4 to 2.6
Is this the question you are trying to ask?

If yes, then wherever the 2.6 kernel come from, there should also be a corresponding UART driver. Just use that.

If not, then please try to rephrase your question.

I guess you would have to modify the source code, if that is even necessary, put it into the appropriate place in the linux source tree, and build a new kernel &/or modules. Unless there is something different about the interface between drivers and the kernel (seems unlikely, but I don't really know) in linux 2.6, I would bet that the code has not changed. I know the hardware and related aspects have been pretty stable on the PC architecture for decades.
Does that help, or have I missed your whole point?
