The problem is that syslinux incorrectly computes amount of data it
should read to load a kernel. Attached patch fixes this. With this patch
applied I can boot from access floppy. Also tested it with netboot (PXE)
and d-i boot.img. I does not understand however why does syslinux works
with other kernels without patch.
