I guess we should force 8k stacks if the lockdep features are enabled.
Also, Laurent is running "2.6.17-rc5-mm3-lockdep" (per his previous
message), i.e., 2.6.17-rc5-mm3 with Ingo's lockdep-combo patch added.
If you're wondering how I conclude the latter from the former, look at
this hunk from the lockdep-combo patch:

And from the same patch:
--- linux.orig/arch/i386/Makefile
+++ linux/arch/i386/Makefile

+cflags-$(CONFIG_FRAME_POINTER) += -fno-optimize-sibling-calls
# temporary until string.h is fixed
cflags-y += -ffreestanding
I would expect that to increase stack usage...
