You can use block lists to specify files (with the attendant problems).
 From info grub:

A block list is used for specifying a file that doesn't appear in the
filesystem, like a chainloader. The syntax is
`[OFFSET]+LENGTH[,[OFFSET]+LENGTH]...'.  Here is an example:


    This represents that GRUB should read blocks 0 through 99, block 200,
and blocks 300 through 599. If you omit an offset, then GRUB assumes
the offset is zero.

You use this block list facility to boot Win$ on an NTFS partition:

title Windows 2000 Pro
rootnoverify (hd1,0)
chainloader  +1
