Comment 28 for bug 187980

Output from Gutsy Live CD with verbose=2. It is really interesting that eject even works with a LiveCD :).
Btw. you are right that sony-laptop was used the first time in Hardy.

eject key output:
[ 3316.064000] sonypi: event port1=0x32,port2=0x21
[ 3348.564000] sonypi: event port1=0x32,port2=0x21
