[CentOS] HAL and mounting volume

Hi, is there anybody understanding HAL?
I use CentOS 4 (RHEL 4) I need set specific mount options for USB flash 
disk.
I found I can do it in
/usr/share/hal/fdi/95userpolicy/storage-policy.fdi

<?xml version="1.0" encoding="ISO-8859-1"?><!-- -*- SGML -*- -->
<deviceinfo version="0.2">
   <device>
     <match key="volume.fstype" string="vfat">
         <merge key="volume.policy.mount_option.uid"
		type="string">nobody</merge>
         <merge key="volume.policy.mount_option.gid"
		type="string">mounter</merge>
         <merge key="volume.policy.mount_option.umask"
		type="string">077</merge>
         <merge key="volume.policy.mount_option.codepage"
		type="string">852</merge>
         <merge key="volume.policy.mount_option.iocharset"
		type="string">utf8</merge>
         <merge key="volume.policy.mount_option.exec"
		type="string">true</merge>
     </match>
   </device>
</deviceinfo>

"lshal" is showing this, but disc is mounted with standard options...

uudi = '/org/freedesktop/Hal/devices/block_4223-CC71'
   volume.policy.mount_option.exec = 'true'  (string)
   volume.policy.mount_option.iocharset = 'utf8'  (string)
   volume.policy.mount_option.codepage = '852'  (string)
   volume.policy.mount_option.umask = '077'  (string)
   volume.policy.mount_option.gid = 'mounter'  (string)
   volume.policy.mount_option.uid = 'nobody'  (string)
   volume.policy.mount_option.noatime = true  (bool)
   volume.policy.mount_option.sync = true  (bool)
   volume.policy.desired_mount_point = 'usbdisk'  (string)
   volume.policy.mount_filesystem = 'vfat'  (string)
   volume.policy.should_mount = true  (bool)
   info.udi = '/org/freedesktop/Hal/devices/block_4223-CC71'  (string)
   volume.size = 130023424  (0x7c00000)  (uint64)
   volume.block_size = 512  (0x200)  (int)
   volume.num_blocks = 253952  (0x3e000)  (int)
   volume.is_disc = false  (bool)
   volume.is_mounted = true  (bool)
   volume.mount_point = '/media/usbdisk'  (string)
   volume.label = ''  (string)
   volume.uuid = '4223-CC71'  (string)
   volume.fsversion = 'FAT12'  (string)
   volume.fsusage = 'filesystem'  (string)
   volume.fstype = 'vfat'  (string)
   info.product = 'Volume (vfat)'  (string)
   info.parent = '/org/freedesktop/Hal/devices/block_8_16'  (string)
   info.category = 'volume'  (string)
   info.capabilities = 'block volume'  (string)
   info.bus = 'block'  (string)
   block.no_partitions = false  (bool)
   block.have_scanned = false  (bool)
   block.is_volume = true  (bool)
   block.device = '/dev/sdb'  (string)
   block.major = 8  (0x8)  (int)
   block.minor = 16  (0x10)  (int)
   block.storage_device = '/org/freedesktop/Hal/devices/block_8_16' 
(string)

what is wrong?
