Making OpenBSD 4.3 detect a D-Link DWA-110 USB Wireless adapter

I bought a D-Link USB Wireless adapater, more specifically, a DWA-110. I wanted to use the device on my very old desktop with OpenBSD 4.3 installed (I'm currently using that box as a "mini" router at home). Before I bouoght the device, I browsed through OpenBSD's list of supported wireless devices. And, sure enough, DWA-100 has a Ralink chipset that is supported by the rum driver. Now, being an idiot that I usually am, I forgot to check the branch (the driver code is still on -current) and bought the device. By now you probably know what happened next...

Out of sheer desperation, I tried following the commits made to -current that enabled the driver support for this device. Luckily, I got it working - well I haven't really used it much so there could still be quirks along the way.

Below is a simple diff of the modifications that I applied (I would have given a link to the diff file but unfortunately I don't have any place to upload files... you'll just have to make do with this ugly white on black html version of the diff file):
