Working Power Manager in Lubuntu 14.04?

I don't know a lot about those specific cards. I have a similar one in
an old PowerPC iBook, and I am not sure if suspend works with it...
14.04 had some issues with PPC and some kernel modules get messed up,
due to a bug in hw-detect. I haven't had the time to debug it, so I use
12.04... which is unfortunate, as the LXDE components do not get
updated, and there is no PPA for PPC :)
That said, there may be a workaround.
I have found with certain cards you can add a boot parameter (in GRUB2)
that can help.
You may do a quick duckduckgo search to see if anyone else has had this
issue in recent Kernels with your card, and see if you can find anything.
For my current Nvidia card I had perfect suspend with 12.04 and the open
source drivers. Then, in 14.04 they broke and I have to use the
not-as-good closed source drivers, only to have suspend :(
If I have time I will try to check out your issue on the internet, but I
am very busy these days...
