I also have loads of boot issues on my W520. I am using Oneiric though
because breaking my working environment in gnome is not an option and
not what I get paid for on my day job ;-)

	* halt from the command line halts but does not power off
	* The W520 has multiple video modes but only one of them
	  powers up the VGA connector. When using that, boot is
	  a russian roulette. It is not unusual for the kernel to
	  lock up twice before I finally get a boot. A couple
	  times I had to pull the battery to get the BIOS and
	  linus kernel to start playing nice again.
	* I have on occasion seen the sleep problem. It happens
	  in particular if I walk away from the machine and it
	  is on a vt rather than gnome; but it has on occasion
	  happened in gnome as well.

I have gotten into the habit of always shutting down when I
travel from the dual screens at home to the dual screens at
work because linux gets tied up in its knickers if I do,
if it wakes up at all.

Things do work better if I am on the factory BIOS graphics setting,
which I use when travelling, but as I said, in that mode the VGA
port is turned off.

Since I have no intention of upgrading from Oneiric at this
time, I have not reported these issues. I have just gritted
my teeth, sworn the occasional general curse and got on with
work.
