There is a schematic for an ATmega128 dev. board on www.olimex.com that shows the
connections.

I would try using AVRstudio to program fuse bits. The options are detailed more clearly.
I had a lot of problems with Ponyprog messing up fuse bits.

Hallo All,
First of all I agree to use AVRStudio... it's free so why not! And 
than you indeed have to use PE0 and PE1! 
It's quite easy: in stead of PIN12(MOSI) you must connect MOSI to 
PIN2, and where PIN13(MISO), it must be PIN3.
So:
In stead of PIN12 --> PIN2,
            PIN13 --> PIN3.
Hope you've got enough info!! Good luck!!

Everytime that ive had problems programming AVRs in my early days it
was due to having disabled the reset pin (used for ISP programming) or
disabling the low voltage ISP programming. Both of these can be
disabled through the fuses, but ISP programming cannot be disabled by
low voltage ISP programming. I agree though that it is much easier and
safer to program fuses using AVR studio.
