(Sorry, this is more or less a lengthy "me, too":)

I am observing exactly the same on my T510 (not surprisingly, as it is
basically the same with a different screen size) using Nvidia (in
contract to most other recent mailing list reports, which are using Intel).

>From 8.1-RELEASE to 9.2-RELEASE, suspend and resume used to work with a
generic kernel (I like generic release kernels and freebsd-update) --
except for a short time, which was due to the Xorg port. Especially
9.X-RELEASE were really stable with all the hardware working after
resume (maybe except firewire).

After going to 10.0-RELEASE, resuming would briefly turn the screen on,
but it would go back to black with the power LED continuing to blink (as
it does while sleeping). After a while, I realized that I lost the
non-default option ACPI_PM for x11/nvidia-driver installing 10.0.

With ACPI_PM for x11/nvidia-driver, I had at least one resume with most
of the hardware working: The screen was still unusable being static with
colorful lines, but I could ssh into the machine over wireless.

I have not had time to try 10-STABLE with vt, but from reading various
reports on the lists, that is probably the only way.

I hope there will be a vt enabled kernel on the 10.1-RELEAS media, if vt
is going to be required even for configurations that would work just
fine on 9.X (WITH_NEW_XORG=yes is very usable with x11/nvidia-driver
even without vt).

>From what you said, you already have ACPI_PM for x11/nvidia-driver as it
is listed on the wiki. Have you?
