I'm very happy with the RAlink 2501 usb wireless which uses the rum driver.
The one odd thing I have noticed is I either have to use 'sh /etc/netstart rum0' or have the device plugged in at boot. Using ifconfig to bring up the network followed by dhclient rum0 does not work.
I see several problems with what your doing:
1) It looks like your are using the FreeBSD instructions.
This is what you want for openbsd

2) You have the subnet mask in hex - see openbsd faq above
I would suggest adding the file
/etc/hostname.urtw0
which contains the following syntax
Quote:
inet 10.0.0.1 255.255.255.0 none nwid Borders nwkey 0xab875ab875

Plug the adapter in and either reboot or use the netstart script.
