Strictly speaking, this is not a regression, because the radeon driver with
KMS has never worked correctly for you in this respect, right?

Now, while the ultimate fix would be to rework device drivers so that they
don't allocate memory from their -suspend() callbacks, it's not quite
realistic to expect that that's going to happen any time soon.

For this reason, I'll try to provide a workaround for you.

It depends on the view point. Compared with the pre KMS radeon driver this has
been a regression for me.

Thanks for trying to provide a workaround. I appreciate it.

I work-around this problem for now by using KDE 4.6 activities which make it
easy to close a set of application before hibernating and restoring them back
to their old state after resuming. Anyway, my next notebook will have 8 GB of
RAM and be 64-Bit, so this should not be much of the problem there. Just to
hint at you that a fix is not urgent for me. But I will have that T42 where the
problem happens at hand to test any workaround you provide.

PM / Hibernate: Add new sysfs attribute for controlling reserved memory

The attached patch adds a new knob, /sys/power/reserved_size, allowing you to
set the size of memory (in bytes) to be reserved for device drivers'
hibernation callbacks while counting the number of memory pages to allocate.

Please check if you can set it to such a number that hibernation will always
succeed on your machine.
