madwifi-modules cause kernel-oops (feisty)

[Hendrick Musche]

Binary package hint: linux-restricted-modules-2.6.20-5-generic

I have an IBM T40p with an atheros-minipci card. After not having used it for a while I updated to the newest feisty, and failed to boot up on the next reboot. dmesg on the fallback console tells me that modprobe failed to load ath_pci, cause it produced a kernel oops. Any kernel of 2.6.20 i tried didn't work, 2.6.19 works fine. Sorry for not giving any dmesg-output, but the drive is mounted read-only.
