NVidia PowerMizer issue after suspend

Question

Hello,
my NVidia GeForce 9800 GT just runs fine on Arch. It normally runs in some kind of low power mode with reduced clock frequencies, however when the computer wakes up from suspend, it starts running at full speed until the X server is restarted. nvidia-settings still reports adaptive clocking as enabled, and there is no active OpenGL application that would need that much of power (disabling KDE compositing does not help either). I've got CoolBits enabled to adjust the low power mode's clock frequencies in a way that the GPU can handle compositing with reasonable performance (it is too slow per default), yet disabling it has no effect on the issue.
I'm using latest 295.40 driver, latest X server and the normal Arch kernel 3.3.2.
Any ideas?

I just found a better solution working for my case.
/etc/systemd/system/root-suspend.service
[Unit]
Description=Local system suspend actions
Before=sleep.target
[Service]
Type=simple
ExecStart=/usr/bin/rmmod alx
[Install]
WantedBy=suspend.target
/etc/systemd/system/root-resume.service
[Unit]
Description=Local system resume actions
After=suspend.target
[Service]
Type=simple
ExecStart=/usr/bin/modprobe alx
[Install]
WantedBy=suspend.target
and then just enable them:
sudo systemctl enable root-suspend
sudo systemctl enable root-resume
Thanks, this helped me out. I knew the workaround probably involved systemd but I've yet to dive into how it works.
