The gma500_gfx driver will match certain devices on which it causes incorrect
functionality,
we want to avoid inserting this module, basicallly blacklist it for specific
hardware,
but still allow it to work on other hardware by default; usually when we have
an already working system,
using udev rules would do the job, but since we are building it, it is
impossible to blacklist
a driver when a certain udev rule matches, since rootfs isn't writeable at this
point during boot time,
the solution is to use modprobe install, which runs a certain command instead
of inserting a matching module
this command needs to insert the module manually afterwards and have a flag
--ignore-install
so it doesn't create an infinite loop executing itself everytime it wants to
insert the module,
busybox's modprobe doesnt provide this functionality, so a small hack had to be
used to avoid
the infite loop instead.
