- enable the paging support - redesign of the APIC code TODO: - Currently, we are not able to start user-level applications. - The RTL8139 driver does not longer work. Perhaps, a bug in the output function. - The APIC codes doesn't work on all systems. Therefore, the code is currently disabled. git-svn-id: http://svn.lfbs.rwth-aachen.de/svn/scc/trunk/MetalSVM@326 315a16e6-25f9-4109-90ae-ca3045a26c18
