I've run into this login loop on my z61m Thinkpad with ATI Radeon card.
The workaround by logging into tty, stopping gdm and then using startx gets me into X
After creating a new user and restarting gdm, I noticed that the logon works for the new user, but not for my own account which was working fine before upgrading from Karmic (64 bit).
To me this indicates a problem with saved preferences, but I'm not sure which .xxxxxx directories (or individual files) I need to delete/modify to get my account to work again.
