Till,

[EMAIL PROTECTED]:~$ ls -l /usr/lib/cups/backend/lpd

Just so you know.  I am 90% certain this is a kernel bug.  I see this in 
ubuntu >2.6.22 amd64 and I see it in debian >2.6.22 amd64.  I filed a 
bug report with the kernel devs of debian:

Bug#478062: Info received (Bug#478062: (Kernel >2.6.22.3-amd64  will 
not  print to cups network printer))

If you have access to that, you can read what I have done.  No solution 
as of yet.  I compiled source from 2.6.22 up to 2.6.24-1 and all kernels 
work until you get to 2.6.24 (all amd64).  Same system used for all 
tests, same packages, just different kernels booted.

HTH!
