OK, I have some answer to the latter, but it doesn't seem to work:

[rgheck at rghquad ~]$ dbus-send --system --print-reply 
org.freedesktop.Hal.Device.Volume.Mount string:"/media/disk" 
string:"vfat" array:string:""
Error org.freedesktop.DBus.Error.UnknownMethod: Method "Mount" with 
signature "ssas" on interface "org.freedesktop.Hal.Device.Volume" 
doesn't exist

And yet:

udi = '/org/freedesktop/Hal/devices/volume_uuid_4A56_7B15'
access_control.file = '/dev/sde1' (string)
access_control.type = 'removable-block' (string)
block.device = '/dev/sde1' (string)
org.freedesktop.Hal.Device.Volume.method_argnames = {'mount_point fstype 
extra_options', 'extra_options', 'extra_options'} (string list)
org.freedesktop.Hal.Device.Volume.method_execpaths = 
{'hal-storage-mount', 'hal-storage-unmount', 'hal-storage-eject'} 
(string list)
org.freedesktop.Hal.Device.Volume.method_names = {'Mount', 'Unmount', 
'Eject'} (string list)
org.freedesktop.Hal.Device.Volume.method_signatures = {'ssas', 'as', 
'as'} (string list)

What have I done wrong?
