also computes an incorrect (slightly too large) setup for the RAM and has
exponential (!) complexity by design -- I'm rewriting the whole MTRR
handling.
That sentence makes me whonder if that "slightly too large" might be a
reason for me having to limit the availbale memory to 3067 MB in order to
not having the system freeze? c.f. #3772 (also includes MTRR setup
listings)
