I have a similar-sounding problem on a dv5000 running Lucid with all updates. Fn-F5 works fine to suspend; but then pressing the power button starts the fan and turns on some lights but the screen remains black and the laptop seems insensitive to any input. At the suggestion of various pages found by Google, I tried passing nomodeset, radeon.modeset=0, or i915.powersave=0 to the kernel from GRUB, without success.
