Does the "words" command work? If not, there may be different issues.

First, did you upload also EEPROM file ("filename.eep.hex") as well?
Many control variables etc. are set using EEPROM. 

Or alternatvely, you fuses may be wrong. Apart from the clock, 
there may be something with the size of your bootloader area (BOOTSZ0,
BOOTSZ1) or the "Boot Reset vector Enabled (BOOTRST).

I am using this to determine correct values, I think Erich gave
