[ltp] Hot swap between IDE CD-Rom and Sata drive in Z61p (2.6.22)

[Marc MERLIN]

Howdy.

So, is it even possible? Anyone doing this on a Z or a mostly equivalent
T60/T61?

The details are below, but it looks like the ultrabay makes my 2nd sata
drive look like an IDE drive.

IDE is built in in my kernel. Does it mean I have to rebuild the kernel with
all IDE built as modules (using the old IDE drivers and not the new ones?)

I have 2.6.22.1 and thinkpad_acpi: ThinkPad ACPI Extras v0.14

I have:
> 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 02)
> 00:1f.2 SATA controller: Intel Corporation 82801GBM/GHM (ICH7 Family) SATA AHCI Controller (rev 02)

I read
http://www.thinkwiki.org/wiki/How_to_hotswap_UltraBay_devices

It says that hotswapping doesn't work well with ata_piix, but that's for
ICH6. I'm not sure if ICH7 requires ata_piix too (hard to tell since I have
everything built in the kernel), but I guess this also affects me, and I 
don't get to use the ide-disk driver and instructions at the bottom of the
page above, or am I wrong and can I use hot swapping ide-disk with ICH7 on a
Z61p?

I also looked at
http://www.thinkwiki.org/wiki/Problems_with_SATA_and_Linux
but I couldn't quite tell if it concerns me, or not.

Any other tips?

Thanks
Marc

Interestingly enough, the sata drive shows up as IDE:
