RE: the patch of restore-pci-config-space-on-resume break S1 on ASUS2400 NE

[Yu, Luming]

The following is S1 suspend and resume log for one working case. 

With 2.6.7, after several times of S1 suspend and resume cycle, the box eventually hang on resume.
With 2.6.10-rc3, after One time of successful S1 suspend and resume cycle, the box hang on resume.
With your patch, I always saw S1 resume hang so far.

After applying patch filed at bugzilla
http://bugzilla.kernel.org/show_bug.cgi?id=1588
to 2.6.7 kernel, the second time of S1 resume by hitting power button cause power off . :-(

>From these experience, I'm thinking S1 is totally broken on this box. :-(

Thanks,
Luming
