Yes.

IMO it's amazingly fast, you should give it a try.

I don't use Redhat,but this _shouldn't_ be a problem

Well, feel free ;)
I have put up my (working) configuratin at my Homepage. (/misc/t40p.html)

In the neweset, yes. in test6-mm1 it doesn't for me, though.

ACK.

You need a resume patch (and to recompile XFree..) but then it works with 3=
D=20
and resume.

It works, at least with 2.6.0. cpudyn is also a  nice to have.

unloading before suspend and reloading afterwards does the trick.

No.

I have the same experience, but there are reports where it works.

Never tried.

Your kernel should tell you that while booting!
