I'm having this too, but I have more information on the matter.
The 1555 graphic card is ATI 4500 series. When I installed the 32-bit version on it, the suspend worked out of the box, but not with the 64-bit version. As I have 4GB of RAM, there is no way I'll use the 32-bit version.
The black-screen problem happens with both free and proprietary drivers.
I'm having other problems (xinerama, multi screen) with the proprietary drivers as well, but that's a completely different matter entirely. ;) I wish it was NVidia... :(
I've set "noapic" on the kernel line, in Grub, and after that brightness works but the lid doesn't. Oh dear... :(
Let me know what information you need me to gather.
