Same here. It seems to go into some sleep state, but it doesn't get out
of it. Some laptops have issues with the video card not coming back to
life after suspend-to-ram, but in my (and apparently your) case, it's
worse. AFAIK, ACPI is still under active development, so I'm hoping that
one day, it 'just works'.

I think it's more of an ACPI issue than a kernel-specific thing,
although it may be that some driver is doing bad things. Look at the
ACPI site to find if there is a fixed DSDT for your laptop. You may be
The thing with ACPI is that there needs to be interaction between the
BIOS and the OS. Most vendors apparently only make sure that the BIOS
plays nice with some other OS.
