Shazam!  Dat be some kinda fast machine, dere.

Let's go with that last one.  I was pretty sure I had more physical RAM
in my PWS 433au than I evidently do: /proc/meminfo implies I've got
somewhere in the vicinity of 576 MB, at least 512 MB of which is what I
purchased for the beast back in 2005 for US$96 (4x128MB).  Swap is
approx. 1.5 GB, so you may safely assume the poor machine was thrashing
quite a bit.  Just to get qt4-x11 to build required configuring an
additional GB of swap as a file within one of the filesystems that had
enough free space.  Not exactly a good recipe for efficient performance.
The 433au supports up to 1.5 GB of PC66 RAM in six slots, so I'll try to
find 6x256 MB sticks if I can find them somewhere at a good price.  Back
in 2005, my vendor of choice was http://www.kahlon.com, and they only
had the 512 MB kit (4x128MB).

That sounds like the correct count.  I installed 25 of the packages, and
most of what I *didn't* install was debug packages.

If you have the time/inclination, install "kdm" and see if you can use
it to login without it segfaulting on you.  "kdm" supports other session
types besides plasma-desktop, so you don't have to install the whole
KDE4 infrastructure to do the test.
