Yeah I know those datestamps don't match, it'll work, trust me.

config-BSL20050914

Is a linux-2.6.13 .config file. I cannot stress this enough, it is the config
file from a VANILLA kernel from kernel.org. If you used apt-get, emerge,
yum, etc, to get your kernel source, all bets are off.

vmlinuz-bsl-20050915

Yet another copy of the same BSL kernel with its initramfs compiled directly in.
