Hmmm. To test your driver itself, use the character devices, which are what
/dev/mtd0 ought to be.
When you're sure that's OK, you ought just to be able to load the mtdblock
device (after your driver) and use /dev/mtdblock0 too. There may be bugs in
the mtdblock code, however.
Can you trace and send me the oops that you get if you load mtd, pmc551, then
mtdblock in that order?
Also, it's worth checking that the mtdblock code actually sets the size of the
block device. The kernel might be refusing to pass on any read() requests
because we've left the device size set to zero.
