Ok, I'll try installing 2.6.30 final for ubuntu and report a new bug. As for the fsck, the only time I didn't boot into single user mode and ran fsck by hand was that one. My fstab entry is simple - "LABEL=Home /home ext4 relatime,defaults 0 0", and most errors I had were data corruption after a crash/hang, as most reporters here, so that is why I reported it here. I've now changed the 6th field to 2 to make sure it is checked at boot if needed.
Anyway, as I said I reformatted my sd card as ext3 and won't try ext4 on it until 2.6.30 final, so until then I'll keep quiet.
