The hdparm way resulted in some bad bad bugs some time ago due to the
more or less broken ide stack. This is supposed to be fixed, though.
I think hdparm -R is the option, which is still marked as dangerous in
the readme.
In the hdparm package you'll find /usr/share/doc/hdparm/contrib/, which
contains a README and two scriptst ultrabayd and idectl. They were
supposed to do those things before the ibm_acpi module was created. Not
sure how far the ibm_acpi module takes care of those things - at least
it works well for the integrated ultrabay, you want to make sure that it
is loaded. Have a look into /proc/acpi/ibm then.
IBM-Acpi's homepage is here: http://ibm-acpi.sourceforge.net/
Hope that helps,
cheers
