vl-hot mount devices in /mnt/vl-hot
I am not a hal user, but I think it uses /media
I think if you plug many devices at once and you want them mounted in the same place you have to make custom udev rules for them. Otherwise they will get a name as you plug them (for example sdb, sdc, etc.)

I know hal can do something through xml files but that is all what I know about it.
Sorry I cant be more helpful, I have only one flash-drive so cd /mnt/v<tab><tab><tab> works for me
