Kernel upgrade + ATI catalyst drivers = X not working

Hi all!
Since yesterday, my system worked perfectly, but I did a full system upgrade and, like every time the kernel upgrades (in this case, to 2.6.37 version), the module fglrx didn't work anymore. I reinstalled both catalyst and catalyst-utils, doing exactly as the wiki says and running aticonfig --initial to create the xorg.conf file:

 
Section "ServerLayout"
        Identifier     "aticonfig Layout"
        Screen      0  "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Module"
EndSection

Section "Monitor"
        Identifier   "aticonfig-Monitor[0]-0"
        Option      "VendorName" "ATI Proprietary Driver"
        Option      "ModelName" "Generic Autodetecting Monitor"
        Option      "DPMS" "true"
EndSection

Section "Device"
        Identifier  "aticonfig-Device[0]-0"
        Driver      "fglrx"
        BusID       "PCI:1:0:0"
EndSection

Section "Screen"
        Identifier "aticonfig-Screen[0]-0"
        Device     "aticonfig-Device[0]-0"
        Monitor    "aticonfig-Monitor[0]-0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
        EndSubSection
EndSection

But it seems that there  is some problem with fglrx module that causes a floating point exception, as it says in Xorg.0.log...

I've tried to install catalyst again from the repository and the AUR but always getting the same error.  I've been searching in forums and googling but nothing worked. I even fixed the DisplaySize on "Monitor" section because I read that there was a bug which gave this error, but this didn't work either. I would appreciate any kind of help, I'm totally desperate...
Thank you!

Re: Kernel upgrade + ATI catalyst drivers = X not working

Have you tried this advice from the wiki?

Please ensure that in the "Screen" section you have "DefaultDepth 24" and there is a "DRI" section with "Mode 666" in it.

Also, if you're desperate, you could give xf86-video-ati a shot.

Yes, I tried that but it gave me the same problem. I also tried to add the name of the modules that should be loaded in the "Modules" section...
With xf86-video-ati it doesn't work very well, I have an ATI Radeon HD 5800 and it seems that the not-propietary driver doesn't support this model, some features I need doesn't work with this one, so I need ATI catalyst drivers. Any idea?

Doesnt the Cards from Radeon HD 5XXX are supported in the same way by the FLOSS driver? My Radeon HD 5450 works fine with that driver

Re: Kernel upgrade + ATI catalyst drivers = X not working

pacman -S xf86-video-ati

thats all. Dont forget to blacklist the fglrx driver in /etc/rc.conf and mv your xorg.conf to xorg.conf.backup (you dont need an xorg.conf for the FLOSS driver)
