kernel26-one-dev panics on boot

I have just finished compiling kernel26-one-dev from AUR, the message at the end states:

Add the following entry to /boot/grub/menu.lst:
# (next number) Arch Linux
title  Arch Linux ArchOne Devel [/boot/vmlinuz-one-dev]
root   (hd0,0)
kernel /boot/vmlinuz-one-dev root=/dev/sda1 ro snd_hda_intel.model=acer-aspire

I have added this to /boot/grub/menu.lst (with /dev/sda1 changed to /dev/sda2, my /), but when booting it prints the partitions and then hangs with caps lock flashing, and is unresponsive to ctrl-alt-del. I have changed it to match the syntax of the other lines, line I'm using now is:

kernel /vmlinuz-one-dev root=/dev/disk/by-uuid/2847d38f-b2f3-46e6-a181-4b8052b3d805 ro snd_hda_intel.model=acer-aspire

This results in a panic, however, with the message

VFS: Cannot open root device "disk/by-uuid/2847d38f-b2f3-46e6-a181-4b8052b3d805" or unknown-block(0,0)

I have checked, and the config does indeed support the FS and driver being used:

...
CONFIG_EXT4_FS=y
CONFIG_EXT4_FS_XATTR=y
CONFIG_EXT4_FS_POSIX_ACL=y
CONFIG_EXT4_FS_SECURITY=y
...
CONFIG_ATA_PIIX=y

Here is my menu.lst:
