[ltp] UltraBay hotplug not working with T23

[Tino Keitel]

Hi folks,

I use kernel 2.6.23.13 on my T23 and just switched from the old IDE
driver to libata. I read on
http://www.thinkwiki.org/wiki/How_to_hotswap_UltraBay_devices shouldn't
be a problem with libata.

Now I removed the UltraBay battery and inserted an optical drive and
nothing happens. I also have to /proc/acpi/ibm/bay file, but according
to http://ibm-acpi.sourceforge.net/, the T23 should have bay support.
What I'm missing?

Regards,
Tino
