On my main computer which uses a mcp55 SB too, these values are definately not
the same.. These are board specific values and, as Yinghai suggests in a later
post, they should be fixed in the m57sli specific files (on the other hand I
agree with Torsten that there are no differences btw the v1.0 & v2.0 versions of
the boards regarding these values)
