I've asked the guy from ati about this issue but still no answer.
My main question was "Does the sata port of the atiixp 200 chipset 
always assigned to hdc or not ?"
If yes, my patch is good and generic to this chipset because I'm 
checking first the pci id of the chipset.
If no, we must found a better way isn't it ?

Could you please try putting your dvd drive as slave by setting up the 
jumper on it ? It will be then detected has hdb (my configuration) and 
should works.
