I'm trying to use the -k (or -K) switch to hdparam, which is meant to

But if I do
hdparam -k1 /dev/hda
and then reboot, calling
hdparam -k /dev/hda
to find the "keep settings" status shows that it's now turned itself off
again!
Can anyone explain what's going on?
First up, the program is called hdparm, not hdparam.
As to your problem, you're misunderstanding what the -k and -K flags do:
they preserve certain settings (dmu options for -k, and APWSXZ options
for -K), but only across soft resets (e.g. if the IDE bus gets reset as
part of an error recovery sequence) - there's no reason to expect the
flags to preserve anything across a reboot.
