I've seen a number of threads referencing this issue while using the install cd, but none relating to after the install is complete...

the installation process completes using the live 2006 cd just fine. but on reboot, I get the following (added a -p):

boot: linux -p
Allocated 8 Megs of memory at 0x40000000 for kernel
Loaded kernel version 2.4.32

PROMLIB: Sun IEEE Boot Prom 3.31.0 2001/07/25 20:31
<4>Linux version 2.4.32-sparc-r2 (root@livecd) (gcc version 3.4.5 (Gentoo Linux 3.4.5)) #1 SMP Tue Jul 18 17:45:31 EST 2006
--same line again for second proc--
<4>ARC:SUN4U
ARCH: SUN4U
Ethernet:<MAC address>
Remapping the Kernel... Kernel Command line root=/dev/sda1
Fast Data Acces MMU Miss
{0} ok

This is basically a "follow-the-guide" install with very few changes. The kernel image is 3.6 MB, but I don't believe that's the issue...

Any help is appreciated and please let me know if I need to add more information...

I've had that problem but not with the LiveCD - I've had it after install. I don't recall the specific versions but at the time I booted with the LiveCD and emerged an older version of SILO. Apparently the version in Portage at the time was having difficulty. It has been some time since this happened to me.

Assuming you can boot from the LiveCD, chroot into the installed environment and see if a different version of SILO helps.

Just boot up the LiveCD, mount your recently installed system on /mnt/gentoo and cd into it. You need not to use chroot. If you have a separate /boot partition, e.g. on /dev/sda1, mount it somewhere else like on /mnt/gentoo/boot and copy your /mnt/gentoo/etc/silo.conf into it. Then remount the boot partition as /boot, cd into it and run
Code:
silo -C ./silo.conf

Otherwise, if you don't have a separate /boot partition, cd into /mnt/gentoo and run
Code:
silo -C ../etc/silo.conf

Make sure you get no error messages from silo. You may have to add the -f switch to make sure your bootblock isn't broken. After this, just unmount and reboot. Your system should boot up correctly now.

Here is what my silo.conf looks like
Code:
partition=1
default=linux
read-only
timeout=100

image=/vmlinuz
        label=linux
        root=/dev/sda2


and a listing of my boot partition on /dev/sda1:
