This patch fixes an edge case for K8 raminit. Specifically, it brings the code
in line with the K10 code.
I was trying to use DDR2 800 (CL6) memory on an m57sli, but booting failed.
Marc Jones found this bug (thanks!), which fixes booting with this specific
memory. For the record, it was Crucial CT2KIT25664AA800.
I put the machine through a few days of use. It also succesfully passed a run
of http://people.redhat.com/dledford/memtest.shtml:
