Ah, this explains it.. the basic bootloader built into the kernel images is
apparently not compatible with the Z505 (possibly because it doesn't like the
BIOS emulation done to make the USB floppy look like a traditional floppy
drive during boot). I've never attempted this form of booting a kernel
before, so I hadn't seen this behavior (of course this method also seems to
have different problems booting on my desktop system, too, so..). Had you
managed to make a small enough zImage you would have had the same results.

My advice is to try using SYSLINUX
(http://www.kernel.org/pub/linux/utils/boot/syslinux/) to load the kernel
instead of writing it straight to the floppy, as this is known to work on the
Z505 and is more flexible anyway.
