cannot resume from suspend-to-ram

[Alessandro Guido <alessandro.guido@gmail.com>]

I can't resume from suspend-to-ram on my Sony Vaio VGN-FS215S.
I tryed debugging the thing a little with pm_trace and my dmesg says:

[...]
ACPI: (supports S0 S3 S4 S5)
  Magic number: 4:804:766
  hash matches device serio4
[...]

/sys/bus/serio/devices/serio4/description says:
i8042 AUX3 port

and /sys/bus/serio/devices/serio4/driver/description says:
PS/2 mouse driver

But now I'm stuck, and don't know what to do!

Here is my full dmesg after the reboot (well, not really full, my /var/log/dmesg
is cropped):
