Can you attach a a broken dump as well (2.6.35 without the revert)? Also, please only provide dumps with module option modeset=1.

No, on 2.6.35 without the revert always get a kernel panic or hard reboot and console not shows anything.
The first dump is good and have module option modeset=1 by default.

Does booting with radeon.agpmode=-1 help? This might be related to bug 16581 or bug 16574. Can you try the patches attached to those bugs?

The option radeon.agpmode=-1 does not work and the patches do not solve the problem, the result is always the same as you know.

How much vram does your card actually have (not what's reported in dmesg)? Is it 128 MB or 256 MB? Also in comment 1, are you saying that vga works fine but dvi does not or that neither port works?

I think my video card have 128MB of video ram, but I'm not really sure.
Xorg.log show on UMS:
[ 45.948] (--) RADEON(0): Mapped VideoRAM: 131072 kByte (128 bit DDR SDRAM)
Region 0: Memory at e8000000 (32-bit, prefetchable) [size=128M]
Region 1: I/O ports at c000 [size=256]
Region 2: Memory at ff4f0000 (32-bit, non-prefetchable) [size=64K]
Expansion ROM at ff4c0000 [disabled] [size=128K]
Region 0: Memory at e0000000 (32-bit, prefetchable) [size=128M]
Region 1: Memory at ff4e0000 (32-bit, non-prefetchable) [size=64K]
VGA to VGA work fine here but DVI to HDMI no.
This is the card:
This shows 256MB DDR.
I test git kernel 2.6.37-rc8 and bug persist.
Can you try these two patches:

Now I have new hardware and my old pc is in pieces when I have some time I'll try.
