[ACPI] Good news: video can be revived after S3 on Dell SmartPC (Radeon M6LY) but only with swsusp2

[roychris <roy...@fr...>]

Hello,
I succeed to suspend to ram and to resume my computer with 2.6.9 and 
specific XFree radeon driver but only if I have the last swsusp2 patch.
If I don't have it, I have two solutions :
- Black screen and no resume at all
- Resume normally, but only graphics and mouse work !
I use lvm2. I use fixpci.sh. I unload all modules before suspending.

The first log is when my computer hangs, and the second is when it works 
with swsusp2 patch.

The attached file is my .config.

Thank you.
