It won't introduce new problems, but it might re-introduce old ones.
For example there is a slowly ongoing action to allow boot at 100mA
budget, this will simply work out a lot better with us not powering GSM
from the CPU when it's meant to be off at that time.  So I don't want to
revert it, but -->

| FSO (and therefore SHR) includes Werner's s3c24xx-gpio utility for

| add two calls to bootscript.

I learned the hard way we have no control over the various rootfs /
distributions, many of them like to still issue 2.6.24.

Also, that way we would crap up several rootfs with a workaround for
something that should be fixed only by a kernel upgrade.

I also observed many strange unrelated things getting blamed on Qi by
customers, I guess because there is no LCM feedback at the moment.

So with these things in mind I conclude I should revert it despite it's
obviously the "wrong thing to do" because it's the least wrong thing
overall.
