Thanks for this - it's just what I need!

Unfortunately my 2.6.11.5 kernel patched with mtd/patchkernel.sh, is 
crashing with the following stack trace (I've just jotted down the 
symbols)...

EIP is at nand_do_read
...
nand_read+0x2c/0x30
find_media_headers+0x3e/0x150
nftl_scan_bbt+0x8f/0x360
nand_scan+0x466/0x940
doc2000_count_chips+0x4e/0x60
init_nanddoc+0x34b/0xad0
do_initcalls
...


The MTD section of my .config is below (I removed NFTL because I'm only 
going to be using JFFS2, ok?). Is there anything obviously wrong here?
