eek! I've never gotten around to adding fstype detection for ISO9660, or UDF come to think of it!
It should work if you specify iso9660:/dev/blah instead of /dev/blah

If your kernel doesn't reset the VGA output itself, you should use the reset-vga command so that kexec will reset it for you.
Edit: @milyges: See my post here:

Nice idea
Does it allow network booting?
