I think it exploded again, for some other reason...

I just gave it a try just for grins-n-giggles.  The resulting kernel got loaded
by grub, the screen cleared, and about 5 seconds later it rebooted. Never got
as far as putting up penguin icons.  Tried again with netconsole, early_printk=vga,
and initcall_debug, and it *still* didn't live long enough to produce anything
resembling output.

2.6.25-rc2-mm1, x86_64 on a Dell Latitude D820 laptop, T7200 Core2 Duo.

Attached is my *working* config (I'm using it as I type this).  Changing to
'CONFIG_PROFILE_LIKELY=y' and rebuilding produces wreckage....
