Phew, it's done. And the winner is:
x86_64-mm-i386-stacktrace-unwinder.patch --------8<--------8<--------8<--------8<--------8<--------8<-------- i386: Do stacktracer conversion too
Following x86-64 patches. Reuses code from them in fact.
Convert the standard backtracer to do all output using callbacks. Use the x86-64 stack tracer implementation that uses these callbacks to implement the stacktrace interface.
This allows to use the new dwarf2 unwinder for stacktrace and get better backtraces.

Backing out just this patch from 2.6.18-mm1 (and resolving conflicts manually the obvious way) gets the boot time back to normal (ie. as fast as 2.6.18 mainline) on my Linux gx110 2.6.18-mm1-noinitrd #2 PREEMPT Thu Sep 28 18:48:32 CEST 2006 i686 i686 i386 GNU/Linux machine.
Thanks Tilman
