I have a lot of updates on this thread, but no breakthroughs:

I enabled NTFS support in my 2.6.32 kernel build:
Steps: edit the .config file, added CONFIG_NTFS_FS=y and
CONFIG_NTFS_RW=y
The ADP1 still would not recognize an NTFS-formatted memory card.
I also did more digging into why
NTFS doesn't have this limitation. Adding this to the kernel is not a big
deal.
Also NTFS FS is abstracted by the kernel so bionic should not care what is
below
the bonnet. What needs to be checked is the mount command whether this for
some reason would not allow NTFS mounts.

Try writing something in the ndk (or a command line executable if you
have the toolchain wrapper scripts) explicitly using 64 bit file io.
And compile and test it against a fat32 volume on a normal linux box
first.

No, I'm not sure how to add NTFS to the kernel. If the 2GB
limitations apply to the Linux kernel or bionic libraries, would NTFS
even help? I'd prefer to add 4GB capabilities to FAT32 if possible.
As far as the FAT32 2GB limits, I see _FILE_OFFSET_BITS == 64 in some
files
FAT32 itself is limited to 2GB. If you need to handle files larger than 2GB
you either need to use NTFS or ext3 or higher.

nope.. may be you meant FAT16. fat32 max file size is 232-1 bytes (~4GB).
it looks odd why access beyond 2G should fail. As chris said below, there
I found this bit of info about a 2GB limit in Linux kernels before
v2.4.0 (http://linuxmafia.com/faq/VALinux-kb/2gb-filesize-
limit.html). But Android appears to be using v2.6 (http://

1 byte)

Did you configure NTFS in your kernel?. Think it is disabled per default
(only checked android-x86).
