Blind-typing has no effect (e.g. `sudo halt -p`), still a stubbornly
frozen screen.

What steps did you take to force the use of non-KMS code? Would that
be passing "nomodeset" to the kernel when booting? (tried that also,
to no effect).

I did learn a bit more running OpenBSD -- passing "disable radeondrm"
at boot I was able to successfully suspend and resume fine. The only
wrinkle is that the back light would turn on right after everything
went to sleep [1]. Well, that and no video acceleration.

Grasping at straws:

I read a post [2] mentioning the "Thinkvantage Configuration Utility".
Evidently you need to boot into Windows to run this utility. This was
for a different issue, but I'm wondering what configurations are in
there and where they are stored ... machine settings not available
via the BIOS? If I can dig up the hard-drive that has my old Windows
install on it I may look into this.
