I'm not sure what you're asking for. This is what I see in R-patched; it's very similar to what 2.1.1 shows:

 > sessionInfo()
R version 2.2.1, 2005-12-27, i386-pc-mingw32

attached base packages:
[1] "splines" "methods" "stats" "graphics" "grDevices" "utils" [7] "datasets" "base"

other attached packages:
multtest survival
  "1.8.0" "2.20"

There's no point showing the versions of base packages, because they match the R version. What other information would you like to see?

So far the following reasonable suggestions have been made. I forget where they were posted, so you may not have seen them:
