Hi,

after I stumbled across some forum post on how do something with the mac 
address of a network device, I can now tell that my device is working again 
on linux-2.6.25-gentoo-r1 with the patch applied. Unfortunately I haven't 
been able to make it working right after booting, rather I need to 
1. rmmod zd1211rw 
2. modprobe zd1211rw
3. ip link set wlan0_rename address my_mac_address

wlan0_rename is the network device name of my wlan dongle, which is 
automatically generated.

The errors I get from dmesg regarding the registration of the device are as 
follows:

zd1211rw 1-8.4:1.0: zd_chip_read_mac_addr_fw()
phy0: Selected rate control algorithm 'pid'
phy0: Failed to initialize wep
zd1211rw 1-8.4:1.0: probe() couldn't register device. Error number -12
usb 1-8.4: reset high speed USB device using ehci_hcd and address 4
zd1211rw: probe of 1-8.4:1.0 failed with error -12
usbcore: registered new interface driver zd1211rw
zd1211rw initialized

This is what dmesg tells me after getting the device to work:

zd1211rw usb_exit()
usbcore: deregistering interface driver zd1211rw
zd1211rw usb_init()
usb 1-8.4: print_id() 1582:6003 v4810 high
usb 1-8.4: reset high speed USB device using ehci_hcd and address 4
zd1211rw 1-8.4:1.0: zd_chip_read_mac_addr_fw()
phy1: Selected rate control algorithm 'pid'
udev: renamed network interface wmaster0 to eth4
zd1211rw 1-8.4:1.0: probe() successful
zd1211rw 1-8.4:1.0: phy1
usbcore: registered new interface driver zd1211rw
zd1211rw initialized

Maybe someone can give me a hint on how to get things working automatically 
after booting. If not, I hope these notes might be useful for somebody.
