Not sure what you mean - my problem is figuring out what to put into the  
file/whether what I have now is correct as I couldn't find any examples in  
the documentation. I believe editing the interfaces file is the supported  
way of configuring the network, unless I missed something (CLI  
networkmanager?)

No. I moved from debian specifically to natty to get a newer kernel which  
contains a driver I need. Googling around, it seems to be a common issue  
introduced in maverick which can be worked around:

Either the documentation is wrong or the use case is not addressed and not  
supported, or there's a bug that needs fixing (possibly reporting).
