 We cannot mount mmcblk0p1 as ext3 due to a feature incompatibility with
 the ext4 driver.  This was seen with 11.3.0 os18 for 1.75.

 This is definitely not fatal, but I don't know if we would have to repair
 the ext3 journal or similar later on should we then get a kernel which
 does not have this issue.

 The kernel in use is kernel-3.0.0_xo1.75-20111203.2238.olpc.e710c80.
