Subject: [BUG] crash - module radio-sf16fmr2 and esp interfere

same with radio-sf16fmr2 and esp

after repeatedly modrpobe/modprobe -r  radio-sf16fmr2,  i can hang my system when loading esp afterwards

before loading esp, doing a "cat /proc/ioport" segfaults

this is with 2.6.24rc6 and also with 2.6.22

i have found these issues by running some (probably sick :D )  module load/unload test across all modules
