When intel k3 chips power up, they are locked ba hardware and the
sequence must be issued to unlock to be able to erase something.

On a first look I put it among the AMD flash_unlock_seq function, which
does something similair I thought.

Well, sounds also reasonable. But am I blind? Where is the code, which
unprotects something, when "protect off x:y-z" is issued?
I agree, an Automatic unlocking is... 
But I still need this "protect off x:y-z" with my provided code, the
chip comes up with all sectors (RO) stillm and they _are_ (RO).
Only after manual "protect off x:y-z" I can erase something.
Before I could _nothing_ write to the chip. Well, I could but nothing
happened. Kinda hardware locked.
