That would mean only a new hardware version could fix it. Let's not
give TI a reason to do this (ie. write apps to flash without validating
them, allowing the execution of apps not signed for your calc).
I'm not too sure if TI would appreciate somebody modifying ROMs
(like replacing some routines with NOPs).
