Probably, though I thought this was also supported in more recent 2.4.x too. 
I got it going on my 2.4.27-based PC. This should be a pretty simple 
back-port though.

block_isbad and block_markbad push the bad block marking & detection into the 
mtd because different devices have different bad block marking strategies.
