SOLVED: Only 3.6gb of 64gb RAM recognized by 64bit squeeze

Summary: Debian Squeeze 64-bit was not able to use more than 3.6GB RAM. Linux showed the problem as MTRR not covering all available RAM. MTRR problems can be fixed by kernel if MTRR repair is enabled, e.g. in the 3.2 kernel. However, the using the backported 3.2 kernel resulted in kernel panic.
