Funnily enough, when I started the laptop up today this problem
disappeared. My best guess is the motherboard or wifi card got confused a
bit through a combination of reflashing the chipset and a warm reboot.
Starting it up from scratch made everything come up OK. 

After some messing around all night (with some help from the lovely
#debian folks on Freenode) I'm pretty sure I've reached the same place as
you have - I can associate to the access point, but it then flip-flops
between associated and unassociated. You haven't found a solution to this
yet, have you? 

Some debugging output is included below.

There is more, but it's all much of a muchness from that point on. So,
what's up with all this? 

Thank you,
