Yes, but you would need to use two configuration files. In that case,
you can either run two wpa_supplicant processes or use a single process.
wpa_supplicant -ieth0 -c/etc/wpa_supplicant-wired.conf -Dwired \
-N -i wlan0 -c/etc/wpa_supplicant-wireless.conf -Dwext

Switch may or may not filter out some frames or link events that may
make this a bit difficult.. Hub would be more likely to work, but that
would get quite confusing if there were multiple hosts behind the single
switch (a) port.
You should be able to run a sniffer (e.g., ethereal) on the ethernet
port and see whether EAPOL frames from the switch (a) are visible begind
the switch (c). You can try to trigger switch (a) to start
authentication by unplugging and replugging the cable (b) from (c).
