Typically in Debian the patches and source are in a deb repository (I would guess for Ubuntu in either the universe or multiverse src repositories). Last time I messed with a patch I think it was called kernel-patch-2.4.27 or the like. Try apt-cache search patch and see if you see anything like "linux-patch-2.6" (debian renamed kernel packages linux-image and linux-source instead of kernel-image and kernel-source)
Even though the patch said 2.4.27, it worked fine on the 2.4.31 kernel I compiled. Alternatively, I think you can use apt-file to list the contents of a package and see if it shows you all the patches applied.
Sorry I couldn't be more help.
