(I noticed 50 Hz (the frequency of the power lines here) on
the output of the RS232 adapter when I come near to the adapter,
so I'm sure it really is HiZ)

Just seen that table 2.1 of the data sheet (Rev. 0.1, July 2006)
lists the signal E51_TXD as alt. output for both GPIO06 and GPIO0D.
But GPIO0D/ECRST# (U41, Pin30) would be strange too.

:) Did you also use a B1 as a testing platform?
