Marcin: I take it you are referring to failure to suspend due to vmalloc failures in the nouveau driver? Indeed, Daniel has verified that this problem can be avoided by using a 64-bit kernel or by passing vmalloc=128M to the kernel (see the reference bug in Launchpad for details).
When that issue is avoided the system does appear to suspend successfully, but then hangs when resuming.
