I do, I think, but actually I discovered the reason for this.  It's a 
subtlety of the Linux boot process which I didn't previously 
understand.  Basically the kernel will use /linuxrc as init if and only 
if the root filesystem on the command line is different from the root 
partition.  So if you are using a ramdisk root (and not an initrd), you 
need to put root=/dev/ram0 on the kernel command line.
