No, no.  The drivers don't touch pin config.  It is related to the AC97 parts
of ASoC, however.  Somewhere memory gets overwritten which causes
the DB1300's ethernet and the DB1200's reset code to fail.  I'll see if I
can find out exactly what's going on.  There was something similar in
the ASoC AC97 code 1-2 years ago which caused linked list corruption,
but Liam fixed that pretty quickly.
