You are.  There is no way for PXELINUX to know what Linux is going to 
call the device once it starts -- it may, in fact, not have a name at 
all or depend on the ordering of devices.

PXELINUX could find out what the hardware (MAC) address are of the 
booting device, but there is no convenient way to pass it to the kernel.
