As a temporary workaround I installed udisks_1.0.2-4ubuntu2_amd64.deb from https://launchpad.net/ubuntu/natty/amd64/udisks/1.0.2-4ubuntu2
and disabled cdrom tray locking/kernel polling in udev rules.
And now it is work fine, like was in 11.04. Eject button is ejecting and udisks-daemon is auto unmounting disk after eject.
