I'm using the radeon module with KMS enabled. On resume from suspend, my laptop screen stays turned off. I know that the system has resumed properly because an external display (through hdmi) shows that everything is working.
dmesg attached.

uname -a
Linux NaviLaptop 3.3.4-00112-gc19c1d0 #4 SMP Sat Apr 28 21:20:04 CDT 2012 x86_64 AMD A8-3530MX APU with Radeon(tm) HD Graphics AuthenticAMD GNU/Linux

I have some btrfs stuff merged into this kernel, but other than that, this is completely vanilla.
