Is there an easy way to monitor how many PCI-E lanes are being used? That way once KMS and everything are in and we get more power saving options it'd be interesting to see how it scales (and verify that it's working).

I think agd5f created a patch which would indicate power state (and pcie lane) changes in your xorg log. It's not standard code because it's not considered nice to write an infinite number of lines to the log under normal conditionsTest signature

@bridgman and agd5f
When disabling the function call to change number of active pcie lanes, within the ForceLowPowerMode function in radeon_pm.c, everything works fine.
I can suspend, reboot, shutdown and there aren't any corruptions whatsoever.
EDIT:
Thats with ForceLowPowerMode enabled btw.

ErrorF("Setting PCIE lanes to %d\n", lanes);
to RADEONSetPCIELanes() in radeon.pm.c and it will print the number of lanes every time the driver changes it.
