Hi!

...but there's enough -- or at least it was enough to fit previous
versions. 32-bit machine, so it has highmem.

System is in console mode, very lightly loaded.

Mem: 2054716k total, 736548k used, 1318168k free, 15368k buffers
Swap: 779148k total, 2360k used, 776788k free, 546388k cached

thinkpad_acpi: ACPI backlight control delay disabled
PM: thaw of devices complete after 539.577 msecs
PM: writing image.
PM: Free swap pages: 194166
PM: Not enough free swap
Restarting tasks ...

Aha, and it is the new default /sys/power/image_size .. setting it to
0 lets machine hibernate. I guess the new default is very wrong for
highmem machine...
