Ja, sure! I noticed that it's there already... thank you all!

So as you requested, I got myself a -rc2 tree, compiled and tested
#s2ram and #s2disk. It works!

full log and small test report is here:
http://zefir dot 890m dot com/kernel-testing/
http://zefir dot 890m dot com/kernel-testing/dmesg.2.6.27-rc2.txt

I have no clue what caused the oops (see dmesg), but I think it's
unrelated (look at the time stamps).

Maybe it's got something to do with the fact that I'm using
https://launchpad.net/~xorg-edgers xserver now to have 3d acceleration
working for my radeon X1200 (RS690 builtin) and the drm module versions
don't match. Xserver wants 1.30 but starts anyway. I can't fix this
because the script can't compile the
git://anongit.freedesktop.org/git/mesa/drm modules for 2.6.27-rc2 ....
This creates some unpredictable problems with the X server process when
I log into my account (can't find out what triggers it ... cpu usage
goes to 100%, have to reboot) As a workaround, I could log into a guest
account to do the tests but switched back to my patched 2.6.26-rc5 for
now for everyday PC usage.

BTW, if somebody would like to explain to me, why the simultanious usage
of the GART by drm and as iommu DON'T bite each other, I'd be quiet
interrested to learn.
