I'm using a modified version of Superkarambas CompactMonitor. It is written 
for Linux I think, but easily adaptable for freebsd. 
All I did was moddify the 
~/.kde/share/apps/superkaramba/themes/CompactMonitor/CompactMonitor.theme 
file : 

text  x=435 y=50  sensor=network device="vr0" format="%in KB/s"  decimals=1
text  x=370 y=50  value="Download"
text  x=570 y=50  sensor=program program="netstat -ibh | grep Link#1 | 
awk '{print $7}'" align=right interval=1000

text  x=435 y=65 sensor=network device="vr0" format="%out KB/s" decimals=1
text  x=370 y=65 value="Upload"
text  x=570 y=65 sensor=program program="netstat -ibh | grep Link#1 | 
awk '{print $10}'" align=right interval=1000

Add
graph x=370 y=30  sensor=network device="vr0" format="%out" w=200 h=15 
color=255,127,127 interval=1000 max=100
graph x=370 y=30  sensor=network device="vr0" format="%in"  w=200 h=15 
color=127,230,180 interval=1000 max=100
if you want to add a graphic representation and change the "vr0" according to 
your (ethernet) device.

It works for me with kde 3.5.8 on 7.0-stable.
