No, I am afraid it is not. The average user has no clue. Even if that
is not the problem, the user never knows for sure he has encountered
the worst case. If you really have drivers that have exceptionally
large memory requirements (eg. you need to copy video ram), you
should tell the system through struct driver and do accounting at
probe and removal of devices.
