btw, I have some code almost ready for sata_nv to add proper suspend/resume support. Unfortunately I have trouble testing it, since STR doesn't work on my machine since, guess what - the video doesn't come back! It doesn't even take the monitor out of standby mode. None of the acpi_sleep options seem to work, and vbetool appears to helpfully segfault on any operation so that's out. This is an NVIDIA SLI setup so that probably makes things a bit more complicated.
In any case, it should be better than what we have right now for suspend/resume support in sata_nv, namely the "do nothing, won't work (at least not for CK804 and later)" implementation..
