i cannot get diseqc to work either
this is with 2.6.11
i've used the kernel dvb drivers and the linuxtv cvs
i've asked questions on the linux-dvb list but have never got an answer
from googling around it does appear that there is a bug in the diseqc surpport 
(something to do with timing calculations) in the 2.6 version of the drivers. 
but nobody seems bothered to fix it and i don't really know how to.

unless this is all compkete rubbish and i have either a broken nexus-s or two 
broken switches.

so all i'm really saying in a very long way is "me too"
