Installing gentoo: kernel panic


I previously had slackware 10.2 and windows xp on my computer, with lilo as my bootloader. I decided it was time to update my slackware, but rather than update it, I decided to switch to gentoo instead. I also decided to get rid of XP, as I was rarely using it anymore. Anyway, I was following the gentoo handbook install guide, and everything seemed to be going perfectly. I finally finished setting everything up and rebooted. Grub loaded fine, but when I tried to boot gentoo I recieved a kernel panic. The last three lines of output were:

Cannot open root device sda2 or unkown block (0,0)
Please append correct "root=" boot option
Kernel panic - not syncing. VFS: Unable to mount root fileystem on unknown-block (0,0)

My partition scheme looks like this ( I use a 250G sata hard drive ):
/dev/sda1 = /boot
/dev/sda2 = /
/dev/sda3 = extended
/dev/sda5 = /usr
/dev/sda6 = /opt
/dev/sda7 = /home
/dev/sda8 = swap

My grub.conf file looks like this:
timeout 30
default 0
fallback 1
title Gentoo
root (hd0,0)
kernel /boot/kernel-2.6.18-gentoo-r6 root=/dev/sda2
initrd /boot/initrd-2.6.18-gentoo-r6.img

While I consider myself an intermediate linux user, I am completely new to grub, so that is a possibilty as to where the problem lies. Any help would be greatly appreciated.

Edit: Oh yeah, all my partitions use ext3, and I have support for that compiled into the kernel.

Stolen from the Gentoo handbook...
http://www.gentoo.org/doc/en/handboo...p=10#doc_chap2

Try this...
kernel /boot/kernel root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sda2

I never got the hang of using an initrd so I really cant attest to the validity of this. Hope this helps
