Thanks, besides using OpenKey() correctly, I found that the values did 
indeed have to be ints... here's a working function:

def log_limits():
     logs = ['Application', 'Security', 'System']
     vals = {'Retention':0, 'MaxSize':10223616, 'RestrictGuestAccess':1}
     for l in logs:
         x = r"SYSTEM\CurrentControlSet\Services\Eventlog\%s" % l
         key = OpenKey(HKEY_LOCAL_MACHINE, x, 0, KEY_SET_VALUE)
         for n,v in vals.iteritems():
             SetValueEx(key,n,0,REG_DWORD,v)
         CloseKey(key)
