You may add those devices to fstab, much like partitions:

/dev/sda1 /mnt/pendrive vfat noauto,users,rw,umask=0000 0 0
/dev/sda2 /mnt/pendrive2 vfat noauto,users,rw,umask=0000 0 0

the key is that "users" param, to allow normal users mount and umount 
filesystem; I very often use static mount points and edit fstab instead 
of using HAL for this, but HAL itself respects fstab configuration too

all parameters are listed in mount docs, but since those are removable 
media, security isn't very important
