Andrew,
First make sure you are passing the correct boot args to the kernel:
root=/dev/ram0
Is this echoed by the kernel during boot?
Also, make sure you have 'Second extended filesystem' support
('CONFIG_EXT2_FS=y' in .config) compiled into your kernel.
That's really all I can suggest without more information.
