Well the truth is, that I use this little tweak from 2.6.26-rc and first cpu having PAT was P3 XEON. And because Intel has backward compatibility, it is safe to use it.
I don't have any problem with loosing data or any suspend/resume problems with this.

Sorry, it doesn't work that simple. There are lots of errata in CPUs, and data loss is too critical.

You're of course welcome to run whatever you want on your machine, but we have to be more careful.
