Hmmm that's very odd, these staments (comments removed for clarity):

EE_ROMDATA      CODE    0xF00000        ; data resides in onchip eerom
        DB      0x03,0x01,0x05,0x05,0xDC,0x00,0x00,0x00,0x00,0x00,0x00,0x00
        DB      CALC_LOW_BAUD(9600),0x03,0x00

Generate this in the hex file:

:1000000003010505DC0000000000000005030000FE

This has worked in previous projects.
The project above is assembled/linked for an 18F452.

Where did you find the information that only even adresses is accepted ? =
