Well, yes and no.
We use portage, which is gentoo's package manager - very cutting-edge, compilation heavy, and optimized to save that extra 5% on your computer's speed - unfortunately due to this, the mindset and needs of most gentoo users is similar to that of a 20-something who's into racing and puts spoilers and decals and new suspensions in his car - not the kind of people who are going to keep around packages that are over a year old. We recognize that this is sometimes quite different from the Sabayon community, and so we've started developing our own package manager, entropy/equo, which though not as optomized, is both much faster and easier than gentoo's portage. Unfortunately, this is still in the beta stages - we don't have old version repositories up yet. (If we ever do go back and put up a 3.26 repository, the command to use to do what you're looking to do is "equo world --update 3.26"). We don't have any old software DVD's or such, primarily because of the way our system works - not yet binary based as SuSE and most other Linux's are. To use quickpkg, just type "quickpkg <packagename>", and to check to see if you have a package you can use "emerge -pC <packagename>". After runnign quickpkg, the binary packages will show up in /usr/portage/packages, and you can just copy them from there to a USB key and then reboot into 3.4f (or loop2) and run "emerge -K /media/ThePlaceWhereIPutMyFlashDisk", ignore the warnings emerge will give you, and enjoy your new old drivers again. As another note, all of this must be done on the command line as root.
A bit more about the way we manage software. Ubuntu and SuSE have release cycles for software - basically they test software on each of their versions, and set up a repository for each version separately - they need to do this because packages that are central to each release are made immutable, and once that package becomes outdated new software may not work properly and so isn't available for that release. We don't do things that way - our system is designed to allow you to update and customize every aspect - there aren't specific software sets for specific releases. Though it would be terribly difficult, you could conceivably just take your old 3.26 installation and update it to the point where it's newer than loop2 - a feat impossible with SuSE or Ubuntu. Because of this, we would never make a repository just for one version - if we set up the "equo world --update" feature, that wouldn't give you access to a different set of software, it would essentially do the same thing as using the update feature on the DVD.
As for where loop2 is, you can find it here: ftp://mirror.cs.vt.edu/pub/SabayonLinux ... op2-r2.iso
just post back if any of this confuses you or you need more information.
