I use the ATI binary drivers with 2.6.11-gentoo-r4, and it
suspends/hibernates just fine on my R50p - BUT I use APM, not ACPI, and I
use the BIOS hibernation, not a linux software-based hibernation method. 
It requires almost 2GB of dedicated FAT space (1.5G RAM + 128M VRAM + a
little).  I don't mind, as it works reliably 99% of the time (and the
video restores just fine now that the newest ATI drivers are playing nice
with Xorg 6.8).

However, I would love to have ACPI support the BIOS hibernation, as it
definitely has battery performance benefits.  I've played a little with
ACPI/swsusp2, but it's just too complicated, not to mention I have to use
a different kernel source/patch set.  I don't mind patching the kernel,
but I like not having to sort out _which_ patches I need...

I guess it's all a matter of preference - and right now, I prefer 2D/3D
accelleration with hibernation rather than the slight battery-life
improvement.  Maybe in another year or two we'll be able to have it all
out of the box :)
