It is not an absolute deal breaker but we are looking for the Thinkpad model providing the best suspend/resume support under FreeBSD. I've scoured the Internet and have essentially learned that the T520 and the T530 might be the best bet.

Hello!
I have Thinkpad E530 (Ivy Bridge) and suspend/resume works very well on
stable and current. The only two issues are:

1. Before suspend I need to switch kern.eventtimer.timer from HPET to
LAPIC (this enabled by default). With HPET it does not resume.
2. With Composite enabled in X11 I need patch [1] to avoid some screen
garbage after resume. Without Composite all works fine.
