I suggest you don't try: there are already quite a few 1.9.0-specific versions of packages on CRAN, and 1.8.x will be history in a couple of months.
I'm not sure I understand the advice here. I have also hit the same problem, and it seems reasonable to me to aspire to maintain a single package which works on both 1.8.x and 1.9.x.
It is not easily possible if namespaces are involved. We failed to anticpate that we would need version-dependent namespaces until rather late and then decided not to set up an elaborate solution when most people affected had already made separate versions for 1.9.0.
