Hi Florian,

I also use a T410 with FreeBSD for some time now but it has no NVIDIA graphics,
so it's running on the intel chipset.

Last year, after some FreeBSD update, the graphics would only be able to use
VESA modes.

After some tests I found out that the intel i915kms module wasn't loaded
automatically anymore.

So I added it to /etc/rc.conf:

kld_list="i915kms"

and after a reboot the graphics did work aggain.

You should be able to test this by entering

sudo kldload i915kms

on the command line and then start the X-server.

Just a guess, hope it helps
