hmmm... What else could I have set up differently though? Could someone who
gets a flat current draw (or at least a low ~5uA draw at 3.0V) please tell
me what their fuses are set to, just in case it's something like that? I'll
try to get some time alone with an oscilliscope or a better/different
ammeter etc to double check it's not that.

uisp -dprog=mib510 -dserial=/dev/ttyS0 -dpart=ATmega128 --rd_fuses

this assumes the mib510 programming board on COM1 (try "uisp --help" for
more options etc)
output from mine (both the 2004 and 2007 versions) looks like so:


Firmware Version: 2.1
Atmel AVR ATmega128 is found.

Fuse Low Byte      = 0xff
Fuse High Byte     = 0xd9
Fuse Extended Byte = 0xff
Calibration Byte   = 0x00  --  Read Only
Lock Bits          = 0xff
    BLB12 -> 1
    BLB11 -> 1
    BLB02 -> 1
    BLB01 -> 1
      LB2 -> 1
      LB1 -> 1


I've tried messing about with the fuses a bit but so far nothing promising
has happened


Thanks for all the help btw!
