Qemu. Try something like:
qemu -kernel your-kernel-image -initrd your-initramfs

Thanks, this worked :).
With socat to create virtualport, I was also able to get the debug messages printed on the virtual serial console.
Actually myself & my friends are trying to help some juniors start of in this path of learning Linux Internals by experimentation, without the need of a separate h/w. Hence I was trying to get Linux booting off Virtualbox with bare minimal filesystem as ISO image (and without the complexity of bootloaders).
And qemu with its speed and simplicity of usage, would perfectly fit the bill. Thanks again for the suggestion :)
