Xorg cannot set to higher refresh rate, but finds proper resolutions

This is solved, but I write it, to give a hint for other users, and I'm writing it from work, so some details may not be exact.
I have:

Amd64 Phenom,
ASUS motherboard, with onboard ATI Radeon HD 4250 video, with HDMI + VGA output. I want to use the VGA output with a CRT monitor.

I've installed:
xorg-server-1.10.3
ati-drivers-11.6

So, I run the 
aticonfig --initial, what have created the xorg.conf.
(You should add to the end the DRI mode 0666, to be able to run with other user (otherwise I experience system froze :( ))
So, with this config, I'm able to startx, and run amdcccle (ati catalyst), but cannot change resolution.
I added modelines with cvt and gtf but no use (keep the modelines, see below)
I found a tiny record in the Xorg.log.0, after many tries:
For some reason fglrx wants to use a monitor named "CRT1" (which is not registered in the xorg.conf!, and xorg.conf is setup to use a different one).
After that, it was easy: rename your aticonfig-monitor1[0] monitor to CRT1, restart the X, and give it a try. It should work now.

Have fun
