I don't see anything in the logs that would allow to assume this.
Most is built right into the kernel.

Modules that were loaded for suspend/resume process (USB unloaded
before trying to suspend, alsa also stopped):

Modules I loaded back later after resume:

snd_page_alloc          7560  2 snd_intel8x0,snd_pcm


Note: the kernel is patched with the two patches I've just sent regarding
      dritek quirk (needed to get any response to they key presses)

Note: suspend/resume is not very stable on this laptop as visible in
      attached dmesg output)
