I had this bug too -- but I had made my NTFS partition with a tool other than the windows XP installer (Partition Manager, on some old boot CD of mine) because in the past at one point I had had a separate issue causing boot trouble and needed to reformat and setup my partitions all over.
I'm curious if the grub developers have tried booting NTFS partitions made by software than the Windows installers -- it's possible they set something subtly differently that doesn't bother windows but bothers grub.
