New description:
In the file [http://cgit.haiku-os.org/haiku/tree/src/add-
ons/kernel/busses/agp_gart/intel_gart.cpp?id=575f2#n439 intel_gart.cpp],
the initialisation of the info.gtt_entries is using a Page size as a
divider while a gtt entry (PTE) is a DWORD.
As a consequence the gtt is not initialised with the scratch_page.
