Have you tried with mkdiskimage -4 /dev/sda 0 64 32?

Btw, have you enabled the USB keyboard in BIOS?
With my award bios, usb key won't boot it is not enabled.

What does it do when you boot on a USB key?
"no bootable partition found" or another message?

Have you trouble only with one specific USB key or have
you tried with another one?
