Monitor does not turn on after suspend

[Marko Ranđelović <markoran@eunet.rs>]

I use Wheezy on desktop computer. I use vesa driver for X because radeon is
not working. After pm-suspend command, computer is like turned off, when press
power button it wakes up, but not monitor and not keyboard.

I tried --quirk-dpms-on, but didn't help.
I also tried kernel options noapic and irqpoll, but didn't help either.

lspci tells my VGA card as:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 6613

Kind regards
