i386/amd64 d-i images for Lenny, Linux kernel version 2.6.32

I happily release lenny-custom-1230. Have a nice new year day.

• Debian 5.0.3
• Linux kernel 2.6.32
• ext4 support
• firmware support

[Update 16th January] Update ISO file (0116) with firmware files firmware-nonfree 0.22 based. I hope some devices such as bnx2, bnx2x, and tg3 work again now.
