That message is coming from a patch that works around a bug in Q2E18.  
The bug was fixed in Q2E19, and as a result, the patch no longer applies.

You can just remove the patch code from /boot/olpc.fth .  The complete 
patch code is as follows; you can remove it all:

patch 2drop erase claim-params
: high-ramdisk  ( -- )
  h# 22c +lp l@ 1+   memory-limit  umin  /ramdisk -  ( new-ramdisk-adr )
  ramdisk-adr over  /ramdisk move                    ( new-ramdisk-adr )
  to ramdisk-adr
' high-ramdisk to load-ramdisk
