This should work, but I haven't done it in a while.

This is the one I was thinking of:

  2003-10-29  Jonathan Larmour  <jifl@eCosCentric.com>

	* src/flash_unlock_block.c (flash_unlock_block): test lock bit
	explicitly - newer flash parts use the reserved bits in the
	returned data.

Probably the tarball in:

   ftp://ftp.ges.redhat.com/private/gnupro-xscale-030422

That source base is fairly old but was in sync with the cvs sources
at one time.
