Take a look here:

linux knowledge from around the net about Thinkpads accumulates here, a
very nice site.  And you can log in and add your own information to be
archived for future people in your situation.

The T410s has Intel graphics:

and there's documentation of Fedora and Suse installs, with few graphics
problems:

My general advice though - usually you're far better off going with a
Fedora or Ubuntu style distro on laptops, the enterprise-based
distributions update too slowly on the hardware driver front for
portable computing needs.

An immediate suggestion for your problem - go in in rescue mode, edit
/etc/inittab, and change the default run level from 5 to 3.  That way
you can get in on console and tweak stuff, issuing a "startx" command to
bring up the desktop at will instead of being forced into a buggy state
right away.
