[slackintosh-users] Bootable CD/initrd problem

I am trying to recreate a Slackintosh install cd with a new kernel. My cd
boots on my B&WG3 with the "c" key held down. When the kernel tries to make
/dev/ram0 the root device, however, it fails and the kernel panics.
Below is some detail on what I'm doing. Any assistance would be greatly
appreciated.
Thanks in advance,
Mark
I use the following to create the image:
mkisofs -hfs -part -map ~/Slackintosh/iso/maps -no-desktop \
-hfs-volid "Yaboot_Boot_CD" -hfs-bless ~/Slackintosh/boot -r \
-o yaboot-cd.iso ~/Slackintosh
The boot directory has:
-r--r--r-- 1 root root 10485760 2006-10-06 15:04 initrd
-r--r--r-- 1 root root 1852 2005-12-31 09:48 ofboot.b
-rw-r--r-- 1 root root 1857228 2007-05-23 15:39 vmlinux
-r--r--r-- 1 root root 145456 2006-08-19 07:29 yaboot
-r--r--r-- 1 root root 518 2007-05-24 11:52 yaboot.conf
The map file reads:
# This mapping is needed to successfully boot and to keep macos
# from treating everything like a text file (ugly!)
#
# EXTN XLate CREATOR TYPE Comment
.b Raw 'UNIX' 'tbxi' "bootstrap"
