My apologies for not providing the information earlier... and for my mistake in supplying the link to my initrd image. I have been bookmarking sites like mad and apparently chose the wrong one...
Here is my linuxrc inside the initrd image (this is the one based off of the evms initrd I found on the web, since it seemed the most complete).
Please note that I still can't get the "/bin/ash" command to work properly, though I'm working on it. I did put in the /dev/tty* and /dev/pt* nodes into the initrd image, but still no luck.

Also note that I have tried "root=0a3f", "root=fe00", and "root=/dev/vg00/root"... the major/minor numbers are listed here (from /dev/hda4 "temporary install" root):

In order to (try to) make this work, I did copy all the "missing" binaries, libs, and dev nodes into the evms initrd image. I would supply that listing, but it would be quite long...
Here is my menu.lst from grub. I've been testing with grub just so that I could enter changes at boot time instead of running "lilo" all over the place.

could you give us some more details about your setup, including actual
lines from your configuration.

There is no initrd image at that location.
What you find there is modified Mandrake rpm to support lvm2 in Mandrake
Linux 9.2/cooker, and has not been tested with anything different than
that.

i saw this problem as well, i don't know if it is caused by some device
file missing in the initrd image or what.
