RE: multiple extended partitions

Hey, nevermind; I found a solution.
Perhaps this is obvious, but I realized I can use the following

hide (hd0,2)
root (hd0,4) # this is actually hda10 in the linux list...
kernel /boot/vmlinuz ro root=/dev/hda10 ....
unhide (hd0,2) 

This gets me a boot out of the 2nd extended partition, and then the
kernel can still access both.
