@Zsg, in order to change the mapping of the phone button, you need to modify the source code and recompile the app.
I'm curious as to which LWP you're using that's really slowing ADW down though, as I've found the drawer performance satisfactory with LWPs enabled (though my animation settings may be different)

Also, I put up the 1.2.1 update file for 1.2 users. It fixes PowerAMP, adds back Car Home, and updates ADW and Terminal Emulator.
But since it's not a full update, I couldn't set permissions on the carhome script, so if you wanna use it, you'll first have to chmod it:
su
sys -rw
chmod 755 /system/bin/carhome
carhome
The full update is uploading still (my uplink is sloooooooooow!)
