What can and cannot be installed on EeePC

Over the last day or two I've attempted the following installs on the EeePC.

1. Despite the major problem I had trying to install the KDE Full Desktop by the manual method, the so-called Easy Way worked perfectly. The whole thing took 2-3 minutes whereas just the download in the Manual Way took 15 minutes.

The KDE Full Desktop is much more useful in my view. Also, the previous problem I had with the desktop web apps only opening in Firefox has been eliminated as I mentioned in this thread.
Also, ctrl-alt-n no longer opens Opera and ctrl-alt-t no longer launches a terminal. However, it's easy to put these icons on the bottom panel which is much more useful.
I also put the CXChromium browser icon in the panel as this had previously to be launched from a terminal. Nevvertheless, despite being readily available, I'm not very inclined to use it as I don't find it at all as convenient as Opera.

2. After my failure with Compiz, I tried Beryl from here. This installed without problems. Operation was, however, disappointingly unpredictable. Sometimes it worked and sometimes it didn't. Even at that, I never managed to get everything to work together as it would, say, in Ubuntu. I'll do more research here.

3. Couldn't get kcheckgmail to install. Sudo apt-get gives this error:

The following packages have unmet dependencies:
kcheckgmail: Depends: libqt3c102-mt (>= 3:3.3.3.2) but it is not going to be installed
Depends: xlibs but it is not going to be installed
E: Broken packages

I believe I could probably get this installed by doing some judicious pinning changes but I haven't tried it yet.

4. I wanted to install gparted as it will be of use in my goal to get Foresight Linux installed on the 15 GB SSHD. However, it too gave an error about gksu wouldn't be installed.
Turns out that there are two versions of gksu available

sudo apt-cache policy gksu
gksu:
Installed: 2.0.0-1
Candidate: 2.0.0-1
Version table:
*** 2.0.0-1 0
500 http://download.tuxfamily.org p701/etch Packages
700 http://http.us.debian.org etch/main Packages
700 http://ftp.us.debian.org stable/main Packages
700 ftp://ftp.uk.debian.org stable/main Packages
700 http://http.us.debian.org stable/main Packages
100 /var/lib/dpkg/status
1.2.5-3 0
800 http://www.geekconnection.org xandros4/main Packages

So the desired higher version was in the lower pinned repos. So, I overcame this by temporarily increasing the pinning of the deb repos to 975. With this, gparted installed fine.
