DLC for Mass Effect 2 seems to work okay. You need an EA account & Bioware account. You have to link your bioware account to your EA master account.
When done, you can login to http://social.bioware.com/user_entitlements.phpÂ and download theÂ content manually.
I have tested the Inferno Armor, Blood Dragon Armor,Â Zaeed - The Price of Revenge (Cerberus Network), Normandy Crash Site (Cerberus Network).
Launch the installer in the wineprefix you have Mass Effect 2 installed, the installer will fail (for me) at cleaning up the install. It is safe to kill the install process.
Once you have started Mass Effect 2, login to the Cerberus Network with your EA account and the DLC will be authorised (you may get a warning the first time)
Please purge your previously wine installation before using that HowTo!
