"nsc" was replaced by "amd" some years ago and is now replaced by the
"geode" driver ... 
sadly the geode situation is a mess atm but we're working on a fix
thought hardy-updates [1] (note that 4.2 is three years old which is
ancient in the OSS world, the amd/geode/nsc driver was "fixed" at some
point for the OLPC X0 laptops which broke it on pretty much every other
system around the time of gutsy development. 
a fixed driver and xorg package is in the ppa [2] that is menitioned in
the bugreport and testing would be appreciated to be sure we really get
a solid version into hardy-updates for 8.04.1)

this is (you probably did guess that already) ldm trying to start but X
failing so it tries to start over and over ...

set SCREEN_07=ldm and SCREEN_02=shell in case you want to have a shell
login on the client ... the ldm.log lies in /var/log on the client
together with the Xorg.6.log
