Known issue. DRM has no suspend/resume support at this time. Also,
acpi_video cannot attach at the same time as it claims the same resources
I have been thinking of looking at this but I want to wait until anholt@ has
some free cycles before attempting it. I'm not familiar with how to save
state for a DRM driver, and I suspect that this depends on the ACPI sleep
state being transitioned in to.
Of course, if we can borrow ideas from Linux or other DRM/DRI platforms, so
much the better.
The question is, are you fully willing to help debug and fix experimental
DRM patches? ;^)

I don't use the UltraNav, but I think takawata-san has already answered this.
