The theoretical maximum is 4GiB. In practice, it'll get far too slow and 
take up far too much RAM before you get that far. I'm not sure what the 
_practical_ limit is.

The minimum is 6 erase blocks, at the moment. It reserves 5 for its garbage

No, that's fine. 

Out of interest, are you using the current code from CVS or the stable 
branch from the 2.4 kernel? The current code should mount a _lot_ faster.
How long does it take to mount?
