Just some suggestions that might (or might not) help.
Play with hw.acpi.reset_video and hw.syscons.sc_no_suspend_vtswitch. You
may find that you need the jhb acpi_video_dpms patch.
I have the following /boot/loader.conf on my T30:
acpi_ibm_load="YES" (This is NOT required for resume, but it is nice for
a few things. It is the recently posted test
version and I don't think it's been committed.)
I have the following in my /etc/sysctl.conf on my T30:
I do notice that I need to switch from my X display to a vty and back
after a resume to get the display back. (CTRL-ALT-F1, ALT-F9)
The SpeedStep errors are troubling. I have not seen any other reports of
