Till Ubuntu 11.10 there the context or edit menu had an option to open a specific folder as administrator. This option came with the package nautilus-gksu. Now it vanished. Does anybody know how to get it back?
Are you sure you mean 11.04? In any event the package is still in the repos & should still work as is through 11.04 (the last version built was "nautilus-gksu (2.0.2-5ubuntu2) natty"
In 11.10 it would install but not work, as of the other day it finally was noted in the current 12.04 build
As far as 11.10 & probably 12.04 the extensions will work fine, you can install the package & either copy or link to proper dir.
Ex. of linking after install
sudo ln -s /usr/lib/nautilus/extensions-2.0/libnautilus-gksu.so /usr/lib/nautilus/extensions-3.0/libnautilus-gksu.so
To copy just replace ln -s with cp.
You actually don't even need to install the package, just place a copy of libnautilus-gksu.so in /usr/lib/nautilus/extensions-3.0
A bug I had on - at this point just hoping someone with auth will mark "Won't Fix"

For 12.04
You can no longer just install the 11.10 package & move or link the .so. -
Easiest way is to download the nautilus-gksu package for your architecture from either of these 2 locations, and save it in your downloads folder
http://packages.ubuntu.com/oneiric/nautilus-gksu pick architecture at bottom of page
32 bit- Direct link from ubuntu.mirror.cambrium.nl
64 bit- Direct link from ubuntu.mirror.cambrium.nl
https://launchpad.net/ubuntu/+source/gksu/2.0.2-5ubuntu2 pick architecture under "Builds"

Once downloaded right click on the .deb > extract here. In the extracted contents, Browse to usr/lib/nautilus/extensions-2.0, inside will be libnautilus-gksu.so
As root (To enter root open terminal and enter gksu nautilus) copy the file from above in to /usr/lib/nautilus/extensions-3.0 folder in your filesystem

Example from terminal, automated commands if you extracted in Downloads folder-
On my 64 bit install downloaded nautilus-gksu_2.0.2-5ubuntu2_amd64.deb & extracted right in my Downloads folder
sudo cp ~/Downloads/nautilus-gksu_2.0.2-5ubuntu2_amd64/usr/lib/nautilus/extensions-2.0/libnautilus-gksu.so /usr/lib/nautilus/extensions-3.0
On my 32 bit install downloaded nautilus-gksu_2.0.2-5ubuntu2_i386.deb & again extracted in Downloads folder so terminal command
sudo cp ~/Downloads/nautilus-gksu_2.0.2-5ubuntu2_i386/usr/lib/nautilus/extensions-2.0/libnautilus-gksu.so /usr/lib/nautilus/extensions-3.0
