ctrl alt sysreq b etc. I tried all kind of things vbetool, passing
acpi_sleep=s3_bios,s3_mode to the kernel. Nothing seems to work.
 
You can see dmesg output and lspci -vv output here

PS: I use kernel 2.18.1 + patch for radeonfb from
http://bugzilla.kernel.org/attachment.cgi?id=9408&action=view

That's http://www.shaftnet.org/~pizza/radeonfb-atom-2.6.18-v6a.diff.

What happens when that patch isn't applied?
