dmesg shows:
dell-wmi: Unknown key 0 pressed
This is a pretty easy fix:
http://www.gossamer-threads.com/lists/linux/kernel/1242512
I tested it on 2.6.33 and 2.6.34 on gentoo and it worked perfectly. This should fix the issue on the studio 1555/1557/1558.
Should the Studio 155x models fall into the dell_new_hk_type category instead?

Just wanted to paste the patch here, in case the mailing list disappears. I haven't been able to test the patch since I've switched back to Ubuntu 10.04 for the time being, but I will be testing the current liveCD on my Studio today.
Fixes pressing the eject key on Dell Studio 1555 does not work and
produces message :
dell-wmi: Unknown key 0 pressed
