"device at 0" ? Or "display at 0" ?

Yep, the standard "vgatext" driver does not support
suspend / resume. Suspending drivers fails at this
point.
A dangerous kernel tunable is "vgatext_force_suspend",
if you set it to 1 vgatext returns "success" during a suspend,
but does not suspend the video hardware.

Good question... I would expect that is resumes
the i8042, mouse and keyboard drivers and the system
is back to normal state.

Hmm, "disk spinning" could be pointing at defect #4603 /
bug 6766845 ?
http://defect.opensolaris.org/bz/show_bug.cgi?id=4603
Can you boot the laptop with option
-B ata-disk-dma-enabled=0
and try a suspend & resume?
