1. Ignore the smaller erasesize - pretend it's 64Kb and force you to erase the
whole lot at once.
2. Treat the parts with different erasesize as different logical devices as
far as the MTD layer is concerned.
3. Change the MTD interface so it can handle variable sector sizes somehow.
As you seem to be implying that the parts with different sector sizes are used
for a different purpose than the majority of the flash device, I'm inclined
to favour #2 for now.
