Hello,

I just start playing around with sleep states on my new laptop :-)

ATM I tried only S1 and with no 'radeonfb' inclued in the kernel, but compiled
as module (even not loaded, as I got an error I haven't solved yet). In this
condition (so no framebuffer), the suspend is always ok, but the screen is never
blanked and it shows
	 hwsleep-0300 [1297] acpi_enter_sleep_state: Entering sleep state [S1]

Here the results for the resume part:

- - with ALSA ('intel8x0', 'intel8x0m' and OSS) it stops at
	Resuming type 'pit':
	 pit0

- - with ACPI (all the modules and 'asus_acpi') it stops at
	hdc: Wakeup request inited, waiting for !BSY...
  as my DVD-RW/CD-RW support 'Hot Swap Function' (I can change it with
  a 2nd battery or HD - not included, obviously), I tried to remove it
  and if it's not present (so no hdc), the resume is ok. I don't know
  which module causes the problem (anyway, in a complete resume even with
  no ACPI modules I've some ACPI error messages as in the attached log)

- - with USB/'ehci_hcd', it stops after trying to resume 'ehci_hcd' (but I repeat
  that the suspend process is ok, so it's a step forward)

- - with USB/'uhci_hcd', I got one complete resume, but I can't reproduce it
  again, now it freezes at a message like
	uhci_hcd: wake-up

- - with 'agpgart'/'ati_agp'/'radeon', all is ok, even from X with the 'radeon' X
  driver and 'r200' DRI driver (which doesn't let 3D support for my ATI Radeon
  Mobility NP M10/9600)

So, I can confirm a positive and complete S1 suspend/resume via X with no ALSA,
no ACPI, no USB and for different S1 cycles (suspend > resume > suspend >
resume, attached the syslog). Just 2 minor problems: 'reboot' doesn't work (it
freezes on the message "Rebooting...") and 'shutdown -h now' acts as 'reboot'.

ASAP I'll try S3 and S4.

Thx, bye,
Gismo / Luca
