Maybe I was confused. I thought the name of the package that ships the firmware
of my card was now firmware-amd-graphics in Sid, not firmware-linux-nonfree
anymore. I first installed firmware-amd-nonfree and encountered an error on X
startup. So I installed the Jessie's package instead. Sorry if I wasn't clear.

I was surprised that Firefox runs reliably (it doesn't on my PowerBook) even
ifvMate is sluggish. I've replaced Mate's default theme with an Arc one and it'
a little better now in Mate.

And I'm very glad you can take time for this. I don't have the skills to do
that. It took me a week to overcome the issues I've had with the booloader and
X11.

Good if it's possible. I can deal with an openfirmware boot command for now.
But not my son or daughter.

umount /dev/sda2

The script and the hfsutils package provided by Roberto on power progress is
quite useful for now.
Thanks again for you time. I'm dealing with the install of ardour : I consider
its install mandatory to get rid of wheezy, because this computer is a part of
my home studio.
Cheers.
