grub and distro questions

Hello All,
Seems like a long time ago that I posted to the group. I've been buried in
books and essays the past few months.

Anyway, I have a new computer and have partitioned the HDD. I have
Slackware 10.0 on one partition and just installed knoppix on another. I
allowed the knoppix installer to write Grub to the MBR (I don't think it
actually gave me a choice). This was no drama as I had added slack to grub
in the past with no problems.

I have tried a few Grub configurations but have not got it to work. My
last try resulted in Slack staring to boot but failing in a kernel panic.
Here's my Grub menu.lst:

title           Debian GNU/Linux, kernel 2.6.11 Default
root            (hd0,3)
kernel          /boot/vmlinuz root=/dev/hda4 ro ramdisk_size=100000
lang=us apm=power-off nomce vga=791
initrd          /boot/initrd.img
savedefault
boot

title           Debian GNU/Linux, kernel 2.6.11
root            (hd0,3)
kernel          /boot/vmlinuz-2.6.11 root=/dev/hda4 ro ramdisk_size=100000
lang=us apm=power-off nomce vga=791
initrd          /boot/initrd.img-2.6.11
savedefault
boot

title           Slackware
root            (hd0,5)
kernel          /boot/vmlinuz-ide-2.4.26 root=/dev/hda6/ ro
boot


Can anyone see where I have gone wrong? The kernel panick message had a
comment regarding Reiserfs which is the filesystem on the knoppix install.
The Slack filesystem is Ext3.

My other question is whether anyone has a copy of the gentoo dvd? I have
wanted to give gentoo a try but hadn't had the opportunity. Now, with a
new computer, perhaps it's time.

Lastly, has anyone used the DamnSmallLinux within windows? I am interested
to see if this works off a memory stick well.

cheers
