kexec solves this for exactly the audience who would need to change command lines. And it solves a lot of other problems/issues.
Implementation/documentation of the kexec solution will take a bit more effort by someone (a few hours, I expect) than hacking in a variable and a means to update it into Qi. But the time/effort on kexec is more generally useful -- it will apply to the GTA01 as well, and even to GTA02 units that do not have the bootloader replaced with Qi. My plate is full (and my day job is creeping into my evenings and weekends), but a kexec solution is something that the community should be able to tackle easily. Mike (mwester)
