I already try only third option of kernel script and i finally read XD
Excuse me for my first post but when i reboot in grub i didn't see the new kernel, but i see only the kernel 2.6.31-18
You must now boot into the new 188.8.131.52 kernel to build the b43 driver.
After reboot, you will need to run part 2 of this script.
You can get it at http://software.6368.co.cc/linux/b43/patches/b43_compile_184.108.40.206.sh
The link is also in my first post on my b43 HowTo thread on UbuntuForums
I have to reboot now?? Awwwwwwww. Oh, well. (After all, it's Linux. Who cares about rebooting :D)
