I'm not David Kelly, but I know the answer...
They're in the linker script.
The simplest way is to the following from the command line:
avr-gcc -mmcu=atmega8 -Wl,--verbose
Replace the atmega8 with the particular chip you're interested in.
The output of this will contain the following near the top:
MEMORY
{
text (rx) : ORIGIN = 0, LENGTH = 8K
data (rw!x) : ORIGIN = 0x800060, LENGTH = 0xffa0
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
}
Those are the addresses used by the linker.
