[ltp] suspend / resume on the R51 (2885RU)

[Yves Dorfsman]

I have an R51 (an 28885RU with the Intel 855GM graphic card), and over the 
past two years, I used it with Gentoo, Fedora 9 and 10, and Ubuntu 8.05, but 
never managed to get it going through a suspend/resume cycle consistently I 
mentioned it on this list a few times and had opened a bug report at 
freedektop.org (http://bugs.freedesktop.org/show_bug.cgi?id=17833).

I installed Ubuntu 9.04 (Juanty) a few days ago, and it suspends/resume 
faultlessly. Ubuntu 9.04 is still a beta version, and I have run into other 
problems (some issues with preseed, and abusing tabs in firefox make the 
machine trash) but, I think the suspend/resume problem with the Intel 
graphic driver, for this card, has finally been solved. I went from minutes 
to revive my machine (from hibernate) to seconds ! I have ran the Ubuntu 
suspend test script 
(https://wiki.ubuntu.com/KernelTeam/SuspendResumeTesting) and have reported 
the success on the feedback page 
(https://wiki.ubuntu.com/KernelTeam/SuspendResumeTesting/Feedback)

As a nice addition, the radio power function (<Fn><F5>) is also working 
(wasn't working on Fedora 9, I don't think I actually tested since, just got 
into the habit of running iwconfig eth1 txpower off) ; which is very nice, a 
lot faster to switch the radio on/off !

Thought I'd let you guys know, in case there are other R51 owners out there.
