Yup. For this reason, I make sure to buy Realtek wireless stuff. As an 
added benefit, urtw(4) doesn't require any firmware, so it's perfectly 
usable in bsd.rd (in fact, I use wireless all the time to install new 
snapshots to my yeeloongs).

I do mean dynamically. I'm sure there are plenty of people in the 
"hoping the right chip is inside the plastic" camp as Jesse pointed out.

Even a dump would be useful for people looking to buy wireless cards.
