Unfortunately, there is no way to mount an ext3 filesystem that requires recovery without replaying the journal and thus causing writes to that partition. os-prober used to replay the journal, but that caused serious data-loss bugs in some cases so we stopped doing that.
The workaround is simply to perform recovery on the filesystem in question using the 'fsck' tool. I regret the need for this, but unfortunately the alternative is worse.
As for why your Maverick system always needs recovery, I can't say. Perhaps it isn't shutting down cleanly?
These are the relevant errors:
EXT4-fs (sda2): INFO: recovery required on readonly filesystem
EXT4-fs (sda2): write access unavailable, cannot proceed
