Dah -- well that explains it.  At the risk of sounding shameless I
remember now it is pointed out that it was actually my intention to put
it in the mach-gta0*2*.c file for that reason.

this stuff is a printk with KERN_DEBUG in the mtd sources, I don't have
loglevel=8 on my kernel commandline and I guess you do.

I just remembered why you can't write to the thing -- you have to do

# flash_unlock /dev/mtd0

first, which is sticky.
