RTL8169 configuring problem

Hi,

I found out that my onboard nic (RTL8169) is supported in
NBSD 3.0 by 
the "re" driver. So I removed the RTL8139 nic I
used so far. However, 
dmesg tells me the RTL8169 interface is not configured. I
touched 
/etc/ifconfig.re0, but it doesn't work. How can I get it
working?

Thanks,

Huub
