Confirmed, Sitsofe ;)
I upgraded to 0802 and I can now reach C3 state with ease, regardless of
snd_hda_intel's status.
Also, the device powers off cleanly after setting
"/sys/module/snd_hda_intel/parameters/power_save" to "10" Neat!
Rather than running sysctl on bootup each time to set these parameters,
I've created a general modprobe.d file that does the same thing. (It
also loads the 700-series specific parameter when needed, which was
another hack I've previously worked on)
/etc/modprobe.d/eeepc:
install snd_hda_intel \
if [ `/usr/sbin/dmidecode -s system-product-name` = "700" ]; then \
/sbin/modprobe --ignore-install snd_hda_intel model=3stack-dig
$CMDLINE_OPTS ; \
else \
/sbin/modprobe --ignore-install snd_hda_intel $CMDLINE_OPTS; \
fi
options snd_hda_intel power_save=10 power_save_controller=Y

Binary package hint: kernel-image-2.6.22-8-generic-di
I chose to file this under the current Gutsy kernel, but this issue has plagued
me since Dapper. Ever since Dapper my laptop wouldn't shut down properly. I
would get the infamous "will now halt" message, but my computer would never
completely shut down. Today I found the culprit: the snd_hda_intel module. If
I manually remove this module (rmmod snd_hda_intel) before shutting down
everything works perfectly. My laptop is a Toshiba Satellite A105-S2716.
I also came across a post from bug #43961 that confirms the same behavior.
Coincidentally, he has the same model laptop I do:

Workaround:
To work around this problem, I created an init.d script to run at shutdown.
All the script does is remove the snd_hda_intel module at shutdown (rmmod
snd-hda-intel) and things work smoothly.
