There is a bug in Sheevaplug uboot 3.4.19 which corrupts the environment
(see console=a0000 and following line above).

This is now fixed in 3.4.27, but two further issues have been found, and
pingtoo has produced fixes -see
http://plugcomputer.org/plugforum/index.php?topic=1134.31 . It appears
that the best uboot is 3.4.27 as patched by pingtoo, available from
http://plugcomputer.org/plugforum/index.php?action=dlattach;topic=1134.0;attach=201 .

Beware though, and it applies not only to 3.4.27, but also 3.4.19 and
3.4.16 and probably earlier, that it appears there is a bug in the SDHC
handling, and that uboot will not be able to handle offsets greater than
4Gb on the card; you should be safe with your 4Gb card of course.
