It is. It's in the 'out of band' area of the data blocks I believe --
see the SmartMedia specs for details.

You need special hardware which gives you access to the raw flash
without doing the translation _for_ you. Most 'card readers' will do it
for you and hence you don't get this option.

No, it's not. Your USB card reader doesn't let you have access to the
raw flash; it has the translation built-in. 

Either implement the full SMTL in your FPGA, or make sure you use
hardware which accesses the flash directly, when writing to the device.
