Blinking cursor after resume from suspend

view story

https://bbs.archlinux.org – I have an "Asus P6X58D Premium" motherboard with ATI Radeon 5770 HD using xf86-video-ati drivers. I've been noticing a problem resuming from suspend-to-ram. It had been working fine until a system upgrade (pacman -Syu) a few months ago. My BIOS firmware is up to date. Initially I would hear the drive spin up to a blank screen an no USB functionality. After setting the BIOS to perform VGA POST after S3 resume, I now get a blinking cursor with no USB functionality. Only thing I can do is a hard reset. Unfortunately, the last thing I get in /var/log/pm-suspend.log is a video suspen (HowTos)
