Nice.

The distro is Mandriva Cooker (development) but we have the same in 
Mandriva 2008.1 Spring.

Now this has not been any problem with kernels older than 2.6.25, so 
it's a regression, isn't it? I mean, shouldn't the module protect itself 
against empty variables?

And that config option also exist in Redhat initscripts ifup-wireless...

Anyway, you found the initial problem, as the kernel now booted without 
an oops, and seems to work, but:
