dev_dbg_reatelimited() without DEBUG printed "217078 callbacks
suppressed". This shouldn't print anything without DEBUG.
With CONFIG_DYNAMIC_DEBUG, the print should be configured as expected.

Went ahead and patched my 2.5.x distro kernel-devel package header, and it works as expected. Apologies about the red-herring with media_build (for those who are not familar with it, = "back-port" wrapper package for building new DVB modules against older kernels).
The distro kernel-devel headers is per installed distro kernel so will be replaced in a week or two... no permanent demage done :-).
