Reinette, This info comes from an openSUSE 11.3 M4 bug report at https://bugzilla.novell.com/show_bug.cgi?id=592399 The kernel is 2.6.33 with openSUSE patches, but none of them should touch iwlagn.

The OP (Cc'd here) reports that it works better on 11.1 (a 2.6.27 kernel) and 11.2 (a 2.6.31 kernel) than it does with this 2.6.33 kernel.
