I did 'ifdown eth0' followed by 'ifconfig eth0 down'; I assume that's
what you meant. I do have some sort of HW switch, but I never touch it.
The machine came up okay. 'ifconfig -a' shows eth0 (unconfigured), but
'ifup eth0' and even 'ifconfig eth0 up' returns 'SIOCSIFFLAGS: no such
device. lsmod shows that b43 is still there. When I then did
'modprobe -r b43' followed by 'modprobe b43', the machine froze - no
screen output after the module insertion.

I've never gotten it to resume correctly. I tried at one time
many / most of the s2ram option suggestions from the
README.s2ram-whitelist, but nothing worked, and I eventually ran out of
patience for the sort of experimenting that required constant hard
power offs and reboots.
