hallo,
trying to use compat-wireless-2.6.33-rc4 together with an ubuntu karmic
2.6.31-18.55 kernel I get the following oops at boot time:

After the following dirty fix my wireless card (iwl3945) works again:

But I am unsure why everything works even without the compat-backport,
perhaps Ubuntu already includes it somehow?
