ec2.conf patch

Disable the floppy devices (fdc0, fd0) and parallel port device (ppc0) on Amazon EC2 instances. They are not present on these machines and output an error on boot (see below);

# dmesg | grep fdc
fdc0: <floppy drive controller> port 0x3f0-0x3f5,0x3f7 irq 6 drq 2 on acpi0
fdc0: does not respond
device_attach: fdc0 attach returned 6
fdc0: No FDOUT register!

# dmesg | grep ppc
ppc0: cannot reserve I/O port range
