Build from src by adding Linux-2.4 to the KERNELS line in the top-level
Makefile, then 'make DEBUG=y world'.

Next, add an early printk hack to linux 2.4 by edditing
linux-2.4.29-xen0/kernel/printk.c to add the following call after the

 HYPERVISOR_console_io(CONSOLEIO_write, sizeof(printk_buf), printk_buf)

Then, 'make dist'.

When you boot the kernel you should see kernel output much earlier on.
