I've done that a lot recently.
Disk has a valid root filesystem, but I want to test new kernel.
So 'pxeboot' the new kernel (MEGALITHIC), then specify wd0a as the
root filesystem when NFS fails to find one.

This did leave an error message about some module not being loaded.

However I did have to make a lot of changes to the server tftp file.
