well, maybe a usb flash stick.  I think that's what I'd do, and it would 
be pretty cheap, reliable, fast, etc.  the only thing on the flash stick 
would be to fetch and boot the usual kernel/initrd configuration, 
so the flash image would never need to change (and would be read-only, 
so presumably not prone to wear.  might need kexec if syslinux/etc can't
be persuaded to behave quite like this.

virtual media via BMC is a good idea, but sounds fragile and vendor-specific
to me.
