So your bootloader is passing fine the tags to kernel.
Kernel command line: root=/dev/ram console=ttyS0,115200
Here you are telling it to boot from ramdisk (maj 1, minor 0)
Kernel panic: VFS: Unable to mount root fs on unknown-block(1,0)
Your kernel fails to mount the ramdisk, since you have RAMDISK driver etc, then the next most likely reason is you are missing the filesystem support in your kernel. For exampel if your ramdisk in in ext2 format then make sure your kernel has ext2 support compiled in (not as a module).
