This happens to me, too - Radeon 7000, same kernel.  I filed bug #246587
against kernel-image-2.6.5-1-686.

I believe it is due to firmware being removed from the radeon kernel module, 
according to this excerpt from the kernel-source-2.6.5 2.6.5-3 changelog:

   * Added firmware loading support (Nathaneal Nerode):
     . drivers/char/drm/Kconfig
     . drivers/char/drm/Makefile
     . drivers/char/drm/r128_cce.c
     . drivers/char/drm/r128_drv.h
     . drivers/char/drm/r128_firmware_loader.c
     . drivers/char/drm/radeon_cp.c
     . drivers/char/drm/radeon_drv.h
     . drivers/char/drm/radeon_firmware_loader.c
   * Removed non-free firmware:
     . R128 firmware: drivers/char/drm/r128_cce.c
     . Radeon firmware: drivers/char/drm/radeon_cp.c

Downgrading the kernel to 2.6.5-2 worked for me.
