In fact, this did not work correctly even in 2.4, except in some very
limited circumstances: either hda only, or hda+hdb. Even hda+hdc
configuration was broken (hda was getting parameters from BIOS, but
hdc was not).

Again, this was broken in 2.4.x too, except for the first IDE drive.
Difference in Megabytes is probably due to rounding and should not
matter (this is output only).
