(back on 3.2.0-0.bpo.2-686-pae 3.2.12-1~bpo60+1*:)
eth0 seems to go down/come up to early/late to get anything useful from netconsole:
[ 745.161322] PM: Syncing filesystems ... done. [ 747.088247] PM: Preparing system for mem sleep [ 747.187932] Freezing user space processes ... (elapsed 0.01 seconds) done. [ 747.204325] Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done. [ 747.220416] PM: Entering mem sleep [ 747.221085] sd 1:0:0:0: [sda] Synchronizing SCSI cache [ 747.222247] sd 1:0:0:0: [sda] Stopping disk
(then nothing)
I may be able to hook up a usb-serial adaptor to try and get more info but it'll take me a bit longer what with all the rewiring fun as I don't have a null modem cable lying around.

"freezer", "devices", "platform", "processors", or "core" pm_test modes all work fine, naturally.
