missing zd1211rx firmware

[Philip Walden]

I just bought a Airlink awll3026 USB wireless adapter as it supposedly 
is supported by the zd1211 driver in FC6.

When I plug it in I get in dmesg:

usb 1-1: Could not load firmware file zd1211/zd1211b_ub. Error number -2
zd1211rw 1-1:1.0: couldn't load firmware. Error number -2
usb 1-1: reset full speed USB device using uhci_hcd and address 2
zd1211rw: probe of 1-1:1.0 failed with error -2
usbcore: registered new interface driver zd1211rw
ath_hal: module license 'Proprietary' taints kernel.
ath_hal: 0.9.17.2 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413)
wlan: 0.8.4.2 (0.9.2.1)

Googling around I see that some file is expected to be found in 
/lib/firmware, but this directory is empty.

Is there some package I specifically need to install to get the 
firmware? I have 2.6.19-1.2911.fc6.
