It should be all there... 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.

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.
