[tlinux-users:08233] Hibernate/suspend on a T200 in Ubuntu Dapper?

Hi!

I have a Toshiba Portege M200 running Ubuntu that used to hibernate 
quite well if I just switched out or X first and pressed Fn+F4 when in 
console. However, lately it doesnt work. When I try to do it manually by 
running (as root) echo -n mem > /sys/power/state, I get an error msg 
that one device does not go down, and this turns out to be video card 
(when looking at bus id in lspci output). I run nv driver, Ubuntu 
Dapper, kernel 2.6.15-27-868.

When trying the nvidia closed driver, consoles wont work so I cannot 
execute echo - n mem there, and when I try in X, I get error that 
Operation not permitted.

Any ideas on what might be wrong, what to do?
