 Please do.  The (bios)firmware should have zero effect on the wireless
 functionality and lots of battery stuff changed in later firmwares so we
 need testing on them to flush this out.

 After you upgrade please try to charge it for a 12-24 hour period.  We
 have had at least one battery here at OLPC that took a long time to
 charge. 3x-4x the normal charge time.  So I need to see if you are just
 slow or if its really not charging.

 Also while its charging boot up the laptop periodically and see if 'cat
 /sys/class/battery/psu_0/capacity_percentage give you a increasing number.
