The BOOTVER (which gets tacked on to the kernel command line,
incidentally) does seem to indicate the bootloader revision. I verified
the 1.01 and 1.10 versions on my Linkstation for the original and
updated firmwares respectively. Some other values are found at [1] and
are of interest for other boxes.
I've attached an updated patch, including a check for a minimum BOOTVER
of 1.10. I don't know precisely which versions exist in the wild but
that is the lowest version I've encountered that is known to work.
Thanks,
Ryan
