Here's some more suggestion to get both suspend and hibernate working 
well with fglrx 7.12 on gutsy, with no Desktop Effects:

in /etc/defaults/acpi-support:
MODULES_WHITELIST="fglrx"
MODULES="usbhid,uhci_hcd"
SAVE_VBE_STATE=false
POST_VIDEO=false
DOUBLE_CONSOLE_SWITCH=true

The usbhid and uhci_hcd are useful if you have a usb keyboard, printer 
or camera, but not necessary if you don't.

It's working well here with these changes.  Now it's as good as radeonhd!
