Comment(by wad):

 OK, I think we found the next hardware bug that was stopping us.  Changing
 C253 to 0.01 uF decreased the rise time of the +3.3V supply from 4mS to
 0.4mS, and fixed the problem that cjb identified with the card detect
 debouncer not settling for a long period of time.   Once applied, there is
 no need for increased kernel debugging levels.

 The entire hardware ECO required to fix is described at:
 http://wiki.laptop.org/go/XO1.5_WLAN_SR_ECO

 Leaving this open until we've done sufficient testing to verify this fix.
