New kernel update breaks wireless

[Andrew Robinson <awrobinson-ml@xxxxxxxxx>]

I just let PUP update the kernel on my laptop to 2.6.22.1-32.fc6. When I 
boot into that kernel, my wireless interface fails to start. When I run

$ ifup eth1

I get

SIOCSIFFLAGS: Operation not supported
Failed to bring up eth1.

I've looked, but I cannot find any reference to the variable 
SIOCSIFFLAGS. Anyone know what's wrong and how to fix this?

Thanks!
