R770 (Radeon 4850) screen/buffer corruption when waking up from sleep mode

Description
If I put my computer in sleep/hibernate (doesn't seem to matter which one) the screen gets corrupted with colors everywhere. It does update, and things jump around when I try to press buttons, bring out menus, etc. It's like the drawing buffer is all jumbled up and it's reading/writing from/to the wrong place.
When something is updated, it's like I can see the picture/pixmap/icon for a fraction of a second, but then it's corrupted again.
If I move the mouse continuously over a menu, to update the highlighting of it, I can see at least where I am on the screen. But the fonts are complete garbage, and it's unreadable. Perhaps I can photograph the screen if it's needed. I haven't tried taking a screenshot.
I'm using Gentoo, 3.11 gentoo-kernel, with Systemd and Gnome 3.8.
The TTY:s are not corrupted, so I'm able to switch to a TTY without problems.
