Just because the guys who made your hardware chose to use flash memory instead of doing it at the hardware level should give you the right to modify it in whatever ways you see fit?
Yes? You paid for it, it's yours to modify as you see fit.
Are you going to demand for ATI and NVidia to release the entire schematics of their video cards so you can make a few changes and build your own custom video card?
Quite honestly, yes, they should be released. There's no good reason for them not to be.
