If you can try nouveau again, does booting with nouveau.noaccel=1 added
to the kernel command line in grub fix it?

This seems to be related to this problem:

** Summary changed:

+ [GT216] random interface freeze

** Bug watch added: freedesktop.org Bugzilla #26980
   http://bugs.freedesktop.org/show_bug.cgi?id=26980

** Changed in: xserver-xorg-video-nouveau (Ubuntu)
       Status: Confirmed => Incomplete

** Description changed:

  Binary package hint: xorg
  
  I have used 9.10 and earlier releases on this hardware daily with no
  problems, but after an upgrade to 10.04 I experience the following
  problem once for every several hours that I use the machine.  There is
  no specific trigger that causes it.  The symptoms are that suddenly the
  keyboard becomes unresponsive.  This includes low-level features like
  activation of the CapsLock indicator light, though Alt+SysRq+o is
  effective.  I am able to move the mouse pointer, but mouse clicks have
  no effect.  There is no corruption of the display.  I am able to SSH in
  to the system, and when I do I notice that xorg is at 100% CPU usage.  I
  have found nothing in any log that indicates a problem, but perhaps you
  will be able to do so.
  
  This is likely related to other recent bugs such as
  https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
  ati/+bug/577236 but I have filed a separate report because my symptoms
  are not exactly the same as any other report.  (For example, I am using
  neither ATI hardware nor compositing.)
