By the way till that, if it helps, I've made some diff about the kernel logs,
between the working maverick's kernel, and natty's, with grep'ing only the
drm/radeon specified lines of both (with natty's I have the one I could catch
with netconsole), then I made an unified diff between them:

-[drm] Initialized drm 1.1.0 20060810
 [drm] radeon defaulting to kernel modesetting.
 [drm] radeon kernel modesetting enabled.
 radeon 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16

+radeon 0000:01:00.0: GTT: 512M 0x0000000010000000 - 0x000000002FFFFFFF
 [drm] Detected VRAM RAM=256M, BAR=256M

-radeon 0000:01:00.0: irq 47 for MSI/MSI-X
+[drm] Supports vblank timestamp caching Rev 1 (10.10.2010).
+[drm] Driver supports precise vblank timestamp query.
+radeon 0000:01:00.0: irq 46 for MSI/MSI-X
 radeon 0000:01:00.0: radeon: using MSI.
 [drm] radeon: irq initialized.
 [drm] GART: num cpu pages 131072, num gpu pages 131072
 [drm] Loading RV620 Microcode
+radeon 0000:01:00.0: WB enabled
 [drm] ring test succeeded in 0 usecs
 [drm] radeon: ib pool ready.
 [drm] ib test succeeded in 0 usecs
 [drm] Enabling audio support

I don't know if it's useful or not, what I can notice is the different irq (46
and 47) but maybe that's natural. Natty's freeze is just after "enabling audio"
by the way.
