I have noticed this too. I thought it happened after a kernel
upgrade, but not sure. It could be related to a newer DRM version.
I just tried a suspend-to-disk after unloading the radeon en the drm
kernel modules. The laptop resumed fine. I then re-loaded the radeon
and drm kernel modules and started Xorg again. However, Xorg did not
start properly, but hogged the cpu. It refused to be killed.
I did notice the following in kern.log: (that's on the re-load)

Jun 14 20:11:19 guava kernel: [drm] Loading R300 Microcode

Normally, that last line looks like this:
Jun 14 20:19:43 guava kernel: [drm] writeback test succeeded in 1 usecs
I don't know whether that's important... it seems one can disable
writeback with a parameter for the radeon module.

suspend-to-ram works fine here too.
