I upgraded my T42 to -current from the 6.0 release kernel but
from what I remember it worked fine with suspend/resume if
acpi_video.ko was loaded at boot time.  My T42 has Radeon M7
-- not sure if that makes a difference.  If I want DRM (for
openGL) the T42 has to be booted without acpi_video.ko.  And
then I usually forget and put the laptop to sleep => instant
reboot on wakeup!

When I upgraded to -current I did not make any changes with
X11.  For what it is worth, this is my /boot/loader.conf
