Exactly! And there is allready a section for that kind of use:
MEMORY
{
text (rx) : ORIGIN = 0, LENGTH = 8K
data (rw!x) : ORIGIN = 0x800060, LENGTH = 0
eeprom (rw!x) : ORIGIN = 0x810000, LENGTH = 64K
fuse (rw!x) : ORIGIN = 0x820000, LENGTH = 1K
lock (rw!x) : ORIGIN = 0x830000, LENGTH = 1K
signature (rw!x) : ORIGIN = 0x840000, LENGTH = 1K
}
The signature section can be used for that. To extend the information
there for the clock frequency etc. is not a problem but must be checked
against other tools which reading these sections.
To write inside this section take a look in
#include <avr/signature.h>
I expect that is no problem to add any needed information behind the
already defined content.

Klaus
