Sleep states fail, console broken

Hello!

I got a compaq N400C, I want to use suspend to RAM.

I do 'echo -n mem > /sys/power/state'. After I 'bootup' the system again, the console I used echo on is logged out.
And the console is initialized differently: Before it used the whole screen, now it uses only parts of it:

-------------------

| BEFOREBEFOREBEFO|
| BEFOREBEFOREBEFO|
| BEFOREBEFOREBEFO|
| BEFOREBEFOREBEFO|

-------------------

-------------------

|                 |
|      AfTER      |
|      AFTER      |
|                 |

-------------------

For a small time (1-2 seconds) the console looks 'funny':
There are coloured rectancles (looks like ascii-art somehow ;-), but it is recorved soon.

As far as I remember, using /proc/acpi/sleep (or whatever the correct path was), failed partly: S1,S4,S5 returns like invalid values, S2/S3 work partly.

But as far as I understood, using /proc/acpi/sleep is deprecated anyway?

Sincerly,

Nico
