As I said, my suggestion is to use FATFS for strict compatibility.

I don't think so. At least you think it's a problem of the ext2 xfs
driver. I disagree in this point.

There are no special routines for TOS domain at all.

Oh, just that you can get wrong results because one application access
foo.bar and another access FOO.BAR (not to speaken that it's pure luck
*which* of these files get's opened by an TOS application).

No, please look into the source to see what's going on in MinixFS.

I disagree that it's a problem of the ext2 driver. The compatibility
operations belong to the kernel there it can be handled in a more general
way (and still for all xfs).
