When you say 'the wireless quit working', do you mean that the wl driver
would no longer load, or that it loaded but did not provide a working
network interface?

These messages, together with the fact that neither of the other drivers
(wl or the Windows driver) work, suggest to me that there has been a
hardware failure.  It may just have coincided with the earlier kernel
