Dual ATI card doesn't work - RADEON HD 3650 and RADEON 7000

[Lagrange Marc]

Hi,

I'm trying to setting an dual ATI cards multi-head with a RADEON HD
3650 and a RADEON 7000:

vgapci1 at pci0:2:0:0:	class=0x030000 card=0xe410174b chip=0x95981002
rev=0x00 hdr=0x00
    vendor     = 'ATI Technologies Inc'
    class      = display
    subclass   = VGA
    bar   [10] = type Prefetchable Memory, range 64, base 0xd0000000,
size 268435456, enabled
    bar   [18] = type Memory, range 64, base 0xfd7f0000, size 65536, enabled
    bar   [20] = type I/O Port, range 32, base 0xd000, size 256, enabled
vgapci0 at pci0:1:8:0:	class=0x030000 card=0x0020174b chip=0x51591002
rev=0x00 hdr=0x00
    vendor     = 'ATI Technologies Inc'
    device     = 'RV100 Radeon 7000 / Radeon VE'
    class      = display
    subclass   = VGA
    bar   [10] = type Prefetchable Memory, range 32, base 0xc8000000,
size 134217728, enabled
    bar   [14] = type I/O Port, range 32, base 0xc000, size 256, enabled
    bar   [18] = type Memory, range 32, base 0xfd6f0000, size 65536, enabled

But i can't get both working, with 'radeonhd' for both cards, get X
started but can't get the radeon 7000 working, wth 'radeon' for both
blinking cursor -> no X, and 'radeonhd' for HD 3650 and 'radeon' for
the radeon 7000, blinking cursor too...

My Xorg.conf:
  http://banane.rhaamo.li/problem_ati/xorg.conf

The Xorg.log.0 (with 'radeonhd' for both):
  http://banane.rhaamo.li/problem_ati/Xorg.0.log

The 'xrandr' output when 'radeonhd' for both:
  http://banane.rhaamo.li/problem_ati/xrandr

The Xorg.log.0 when setting 'radeon' for both:
  http://banane.rhaamo.li/problem_ati/xorg.log.radeon_both

If somebody can help me to get this working it will be great :)
