It also appears that there is a regression in acpid's ability to write log 
files.  My suspend script writes battery usage stats to 
/var/log/battery.log.  Since the most recent update, access to that file 
is denied.

Several records like this appear in audit.log:

type=AVC msg=audit(1127578352.719:7582708): avc:  denied  { append } for 
pid=3860 comm="thinkpad-T4x-su" name="battery.log" dev=dm-0 ino=910036 
scontext=system_u:system_r:apmd_t tcontext=system_u:object_r:var_log_t 
tclass=file
