I can now confirm the following:

$ sudo chvt 2 ; sudo /usr/lib/hal/hal-system-power-pmu sleep ; sudo chvt 7

that command works perfectly - suspend and resumes, and everything seems to work perfectly.
On the other hand, with pm-utils - which I understand is the way currently used:

$ sudo chvt 2 ; sudo pm-suspend ; sudo chvt 7

this will give me: Error: kernel cannot suspend to ram.
Now since with the first command all works fine, obviously the kernel does support suspend, so the faulty part must be some interface between pm-utils and PMU on powerpc.

Please notice that the vt switching is necessary on this machine (radeon open source, r300) - otherwise suspend works but resume fails. In gutsy that was a problem that wasn't yet fixed, see bug: https://bugs.launchpad.net/ubuntu/+bug/144305
