problem with linux-2.6.27

Hi!

First of all some feedback: I got Ubuntu 7.10, compiled at76-usb-0.17 for it, installed the firmware and removed the old at76-usb-0.14 version which came with Ubuntu. Then it worked, nearly perfectly. WEP did, WPA not; excellent performance!

Now I installed the new Ubuntu 8.10 and tried to do the same. The new Linux 2.6.27 had changed some interfaces minorly - i adopted them and compiled the adopted at76-usb-0.17, installed the fw, removed the \"wrong\" at76.ko-s from /lib/modules/..., depmod -aeq... -> Result: It worked with the same bad performance as 0.14 (unusable).

Does anyone has an idea what my mistake was or what had changed?
