fglrx: How to load intel driver with various options, e.g. AccelMethod

Hi,

When using fglrx and pxpress on a system with hybrid graphics, how can options be set for the intel device?

Normally in the "xorg.conf" I could just put something like

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "sna"
EndSection

But with fglrx installed the xorg.conf looks like

Section "ServerLayout"
        Identifier     "Radeon Layout"
        Screen      0  "aticonfig-Screen[0]-0" 0 0
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:6:0:0"
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

(Adding an intel device section in here would cause major problems(I get segfaults). I guess because both fglrx/pxpress and xorg try to launch the i915 driver)

So how can I configure options for the intel driver?

Why do I want to do this?

Well aside from the ability to tweak the integrated GPU performance in the usual manner, I have a bug that occurs when UXA is used as the accleration method, but not when SNA is used for the intel driver (even before fglrx is installed on the system). Without fglrx SNA is the default anyway, but fglrx for some reason likes to use UXA.
