The recommended way to do this for modern linux distributions is to write an fdi file for HAL. That way you can specify where the device should be mounted and make it user/auto mountable. For example, here's the FDI file I use for the SONY reader and Kindle:

cat /usr/share/hal/fdi/policy/20thirdparty/10-libprs500.fdi
