I would like this too. Unfortunately, I have no clue on how to detect
that we're plugged into a dock. And it's not even clear that acpi-support
is really the package that should take care of that. After all,
acpi-support is only a set of hacks so that supend/resume works
with as many laptops as possible.

I'm ccing debian-devel to have some more comments on this issue.

What happens currently when you wake it up? Do you have no cdrom at all,
or do you simply have it as /dev/hdc only?

Feel free to provide a patch. :-)

I don't know it it's reasonable to call hotswap systematically after a
resume (if it's installed). 

For everybody: new (co-)maintainers for acpi-support are always welcome as I'm
certainly not the best maintainer for that package (I don't care enough
about it, I simply wanted it to make my laptop suspend/resume). Also such a package
would benefit from having several maintainers with different hardware
