Tried it here on a B3.

>     *  UBI is taking an extremely long time (~50s) to attach to the MTD device on the XO I am currently using for this testing. UBI attach time does scale linearly w.r.t flash size, however the 50s seems wrong. According to this, we should only take about 2 seconds. At attach time I see a warning "UBI warning: ubi_eba_init_scan: cannot reserve enough PEBs for bad PEB handling, reserved 74, need 79" b/c my system partition has 5 bad PEBs in it and this may be related. TODO: Test on another XO.

Also found this, but even then it booted faster into Sugar than the XO
with jffs2, but that one had the jffs2 gc thread taking the cpu, so...

Haven't seen yet any other difference worth of mention, though.
