Log Message:
Pull up following revision(s) (requested by he in ticket #1657):
        sys/arch/i386/pci/pchb.c: revision 1.63
According to http://www.intel.com/design/chipsets/specupdt/290639.htm,
the BIOS bug workaround for the i82443BX chipset's DRAM leadoff timing
parameter is not needed for revisions >= C0, so avoid tweaking that
parameter in that case.
Earlier, this would trigger NMIs on fully memory-populated Compaq
1850R systems, where the BIOS appears to program and require a non-
standard value for this parameter.
Thanks to Chris Ross for the diagnosis and the fix!
