I have tried the new 20070125 version.
However, I did not manage to make work. At least, it compiles.
I have installed, both wpi_fw.ko and the if_wpi.ko, as the README said.
wpi_fw.ko lies in /boot/modules and if_wpi.ko in /boot/kernel.

When, I "kldload if_wpi", here is a small sample of /var/log/messages

Jan 27 10:30:39 vaio kernel: wpi0: <Intel(R) PRO/Wireless 3945ABG> mem 0xcc000000-0xcc000fff irq 18 at device 0.0 on pci6

Jan 27 10:32:19 vaio kernel: firmware_get: failed to load firmware image wpi_fw
Jan 27 10:32:19 vaio kernel: wpi0: could not load firmware image 'wpi_fw'

In kldstat, both modules are loaded.
Then, I have "kldunload if_wpi" (and if_wpi seems to be reload,
automatically, I don't know why). Same problem, it seems that wpi_fw
could not be load (found ?).

As a result, no AP is "associated".


After a fresh reboot, I have reinstall the custom 20070121 version of
mine, and all returns OK.
Another strange thing: when "kldload if_wpi" with 20070121 version, and
then kldstat, I don't see "wpi_ucode". It seems that wpi_ucode.ko does
not need to be loaded, in my case.
My wpi_ucode.ko lies in /boot/modules

After another fresh reboot, I first moved wpi_ucode.ko to another place.
When I "kldload if_wpi", I got the following message:

Jan 27 09:47:16 vaio kernel: wpi0: <Intel(R) PRO/Wireless 3945ABG> mem 0xcc000000-0xcc000fff irq 18 at device 0.0 on pci6

Jan 27 09:47:16 vaio kernel: wpi0: could not load firmware image 'wpi_ucode'

So, it seems that wpi_ucode.ko have to lied in my /boot/modules (the
place where I have also put if_wpi 20070121 version), even if it is not
loaded.
