[uClibc] fstat and fstat64

My apologies, you are correct - I quoted headers from the installed
directory, which were installed by uclibc (in my 2.6 build) therefore
contained *my* patch.

Ok, so there *is* a structure layout change, but it *is* in stat64, not in
stat - because stat keeps the low 16 bits of st_dev in the first two bytes
of the structure (regardless of architecture), whereas stat64 moves the low
16 bits from the first two bytes to bytes[7:8].

Your patch doesn't fix this (it doesn't change st_dev in stat64.)  The
st_rdev change looks right and would work for st_dev too.  The st_blocks
case looks correct too.  I'll test it with the addition of the st_dev fix
(on big-endian only.)
