I'm on ubuntu 8.10-rc with all updates (so I'm on their 2.6.27-7 kernel) 
on Lenovo X200.

I can replicate the problems without X, I get an oops when it comes out of 
sleep (can't scroll up and nothing in the log).

If I shut down X, power down bluetooth (fn-F4) and rmmod btusb and 
bluetooth, I can successfully get the X200 to sleep (by executing the 
/etc/acpi/sleep.sh script) and come back up again properly.

If I have X enabled, power down bluetooth, /etc/ini.d/bluetooth stop and 
rmmod btusb/bluetooth, I still get the problem when coming out of sleep. I 
get a mouse pointer (unmovable), black background, and after 5-10 seconds 
I get hard power down (watchdog?).

I have tried to ctrl-alt-F1 to text console and make it go to sleep to see 
if this works in conjunction with X running, but it seems some X daemon is 
catching/hindering the fn-F4 and ./sleep.sh, so I haven't been able to try 
this.

Anything else I can test that might help?
