Successfull start of vt 7
I'm using kernel 2.6.33-rc2 and compiled the drm and Xdriver myself from the
latest git repos. I have a 5200 with two monitors attached one 1280X1024 the
other 1024x768)
Now starting the Xserver and using it works fine. (much better than the version
which is currently in debian experimental).
But as soon as I start create another Xsession (on vt 8) via kde(4.3.4) change
user I only get black screens.
it is quite hard to get back to a working console, I don't know how I got it,
but I got one back.
With dmesg I see this:

I think at 228 I started the first X session and at 321 I switched back to the
console (VT1).
This would mean at 357 I started the second X Session.
I'll attach both Xorg.*.log files (0 for the first X session, 1 for teh other)
