The patch apparently fixes the problem that I have reported, so thanks a lot, Pavel. After it's been fixed, however, I often get things like that:
PM: snapshotting memory. swsusp: critical section: ..<7>[nosave pfn 0x58b]........................................................................... ............................................swsusp: Need to copy 31927 pages suspend: (pages needed: 31927 + 512 free: 98952) hibernate.sh: page allocation failure. order:8, mode:0x120 Oct 8 14:15:57 albercik kernel: Call Trace:<ffffffff8016eb2d>{__alloc_pages+749} <ffffffff8016ebd1>{__get_free_pages+33} <ffffffff80161a23>{suspend_prepare_image+531} <ffffffff8026d7a7>{pci_device_suspend+71} <ffffffff80161cb6>{swsusp_swap_check+22} <ffffffff802ea112>{suspend_device+50} <ffffffff80120d0c>{swsusp_arch_suspend+124} <ffffffff801610cc>{swsusp_suspend+12} <ffffffff8016222a>{pm_suspend_disk+90} <ffffffff8015fe04>{enter_state+68} <ffffffff802adc0d>{acpi_system_write_sleep+100} <ffffffff80193914>{vfs_write+228} <ffffffff80193a53>{sys_write+83} <ffffffff80110c72>{system_call+126} Oct 8 14:16:05 albercik kernel: suspend: Allocating pagedir failed. It's sort of strange, because there were 250 meg of RAM available, out of 500, at that time.
Anyway I was able to suspend the machine after the above one had happened (I stopped an app occupying some memory and then the box suspended), but then I got a spectacular crash on resume (unfortunately I was unable to save the trace, but I'll try to reproduce it).
