Where have you got this information from? I've never heard of this.

(i.e. Cylinder=0/Head=1
/sector=2 or LBA=40) it seems it does not take care about the disk
geometry. I think it's not correct : the 1st partition should be aligned
on the 1st sector (2nd,3rd,4th partition should be aligned on head*sector
- 1st sector/Head 0).
I believe we don't even know the actual disk geometry at this point, let
alone that it probably cannot be represented with the limited CHS scheme
anyway. Does anyone even care about these alignments still?
