nothing fancy:

default=Linux

image=/vmlinuz
        label=Linux
        read-only
#       restricted
#       alias=1

image=/vmlinuz.old
        label=LinuxOLD
        read-only
        optional
#       restricted
#       alias=2

since i'm not using fb, this one is ruled out.

of course since this is intermittent i can't reproduce it, and it hasn't
happened for a day now. but i'll keep digging to see if i can figure out
what causes it.
