I cannot reproduce this.  I tried:

$ sudo nmap -v --open -p75-85 192.168.1.0/24

I also tried with -d instead of -v, only using a known closed port (85) 
for all hosts, and only scanning one host, but --open worked fine for 
every combination of these.  Maybe SuSe applies patches to packages, and 
somehow that's what messed it up?

Thanks,
