I'm not totally certain of why this is (I don't know enough about the
hardware involved), but I'm told that with this patch some drives will
lose their geometry translation after a reset/unwedge.  After that, the
driver will be using one set of cylinder/head/sector geometries and the
disk will be using another, leading to file system data corruption.

If it works for you, then you're lucky/fine.  It does cause problems for
other systems.

Charles Hannum has mentioned in conversation that he'd like to see a
proper fix for the problem--any takers?
