Dell Studio 1737 radeonhd suspend

Hello smile

Here's what I have:
Dell Studio 1737, Radeon HD 3650;
standard kernel 2.6.30-5, xorg-server 1.6.1.901-3, xf86-video-radeonhd 1.2.5-1, pm-utils 1.2.5-1.

My problem is I can't get it to turn the screen on after suspend to ram.

I've tried:
– pm-utils with all options and various (though not all possible) combinations;
– s2ram with all suggested options;
– hibernate-script with both pm-utils and uswsusp;
– machdep.acpi_vbios_reset=0, acpi.vbios_reset=0 combined with vbepost, hpet=disable.
Results vary from complete freeze to everything's-fine-except-for-the-screen-is-black.
Whenever I got it to work except for the black screen, I've tried typing "vbetool dpms on" and "vbetool post" but without success. Before suspending, vbetool dpms off and on works perfect.

I've also tried different video drivers:
– with radeon (which doesn't really work too well with my card), I got it to successfully resume, except for that it froze when I tried to shut it down later on;
– with fglrx it worked great for a moment until one update broke it all down, and I couldn't get it back to work.

The thing is, I really need this functionality. Please let me know if you need any more information.
