2.6 kernel upgrade gives garbled video (w/o X11)

| Hi all,
I recently attempted to upgrade my kernel from 2.4.27 to 2.6.18 on my
Sarge installation. First off, I had to change my sources.list to use
the Etch packages because of a dependency loop involving libc6.
However, I did the kernel installation w/ "apt-get install kernel-
image-2.6-686" and the installation completed successfully w/ my Grub
configurations updated automatically.
When I restarted the machine and selected the 2.6 kernel, the boot
process proceeded fine (and I could read all the text scrolling by).
But when it came time to display the login prompt (terminal only, it's
a server, so there's no X11) the screen got all garbled. Essentially
all I can see is flickering black and white boxes covering the screen.
However, I can login and reboot the machine - I just can't see what
I'm typing.
Anyone have any suggestions on this one? I tried installing the kernel-
image-2.6-386 on a lark, but I still ran into the same problem. I'm
not passing any special kernel parameters on boot to the 2.4 kernel
either. What am I missing?
Thanks,
Aaron

Why not download and then install 'etch'. When installing etch you can
leave your /home without formatting so as to keep your personal
files intact and then update as necessary from there.

It's not that I want to install Etch, but rather that I wanted an Etch
kernel because I was having issues with the Sarge 2.6 kernel. However,
since my last post, I've reverted to the Sarge packages (after a few
apt-get -f install commands to straighten things out) and rerun the
"apt-get install kernel-image-2.6-686." The Sarge 2.6 kernel (2.6.8)
installs fine, but I still have the garbled console window after boot.

Are you booting into normal text mode, or are you using a framebuffer
console?
What version of libc6 are you using?
What is the specific version of the Sarge 2.6 kernel you're booting
into? (e.g. kernel-image-2.6.8-3-386 [2.6.8-16sarge6])
Please show us the output of this script:
cat /proc/cmdline
/sbin/lsmod
Since you can't operate the computer well when booted into 2.6, you
might consider creating a script that starts during boot-up and collects
this information.
