it will normally be indentical to mounting a camera, as from the direction the PC looks at the device, they are both likely to be generic usb devices.
Code:
mount /dev/sda1 /mnt/usb
is likely to load it, but opnce you plug in the stick, run "dmesg" and assuming mandrake comes ready configured, which i certainly expect it is, then there should be output at the bottom defining where it has been attached to in /dev. sda1 is the most likely place, but it might change between distros. particuarly if using the newer udev /dev system, in which case it might even be called /dev/usbstick or something... still not played with udev myself.
