Sigh, I have found what happens. And it will happen on every 64 bit platform with recent 2.5 kernel.
the internal reiserfs blocknumbers were referred to as 'unsigned long', that's where these
extra blocks of zeroes are from, this also explains all other anomalies.
Except when I make it 'unsigned int' as it ought to be, it still breaks,
only in some other way which I have not understood yet.
(yes, I seem to finally got our alpha to some working state and can do experiments locally now).
