Hello John,
It seems that lilo does something incorrectly with initrd image
if kernel image is around 3MB. I found this when I built Linux 2.6.18
and it failed to mount initrd. Previously I was using 2.6.17.11_64
and earlier kernels with no problems.
I tried loading the same image and initrd from DOS with linld and
it worked flawlessly. Then I loaded the image without initrd
using lilo (this worked) and compared dmesg with DOS one.
The obvious related difference is:
testing NMI watchdog ... OK.
-checking if image is initramfs...it isn't (no cpio magic); looks like an initrd
+checking if image is initramfs...it isn't (bad gzip magic numbers); looks like an initrd
Freeing initrd memory: 1460k freed
Then I built smaller 2.6.18 (excluded some stuff I can boot without)
and it was loaded with initrd using lilo just fine.
More details:

Attached are dmesg outputs from all three boot scenarios:
dmesg_bare - 2.6.18_64 without initrd using lilo, init=/bin/sh
dmesg_dos - 2.6.18_64 with initrd using linld, normal boot
dmesg_smaller - 2.6.18_64s with initrd using lilo, normal boot
