I am pretty sure I didn't recompile after installing the kernel, see:
$ ll /boot/vmlinuz-2.6.35.3-saber /usr/src/linux-2.6.35.3/arch/x86 /boot/bzImage
vmcore.201008232109

I also tried many times with many crashdumps and it never seemed to
work. Could the stripping or bzImage'ing change something?
I would try directly the vmlinux kernel, but it's over 120MB and my boot
partition is smaller than that.
Maybe there's some kernel options that change something in the bzImaged
vmlinux?
The vmlinuz file is a compressed, stripped-down, and otherwise-manipulated
file that is created from the /usr/src/linux-2.6.35.3/vmlinux file -- which
is the file that crash requires.
And the vmlinux-to-bzImage process would not change the compiled-in
kernel virtual addresses that you see if you do this:
# nm -Bn /usr/src/linux-2.6.35.3/vmlinux
If it does, then that's news to me...
