	[Stephane Dalton]  Probably the variable didn't disapear but if it
must be at the beginning of you rommable image, you'll have to create a
section which is the first one referenced by your linker script, you'll have
to use the __attribute__ with the section parameter, for the linker script
you can refer to ld manual and for the __attribute__ the textinfo on gcc is
quite well written.

	Hope it will help a bit!
