I don't see why not. Any DOS gurus want to chime in? The ramdisk_size
kernel parameter allows you to adjust the size at boot time.

I believe there is also some trickery involved with booting from USB
mass storage which will give you a ramdisk by default. It works a lot
like bootable CDs.

It is actually possible to get a BIOS to handle the bootup from a USB key,
so no floppy is necessary. A USB 2.0 key can make the speed more tolerable.
