On some microcontrollers I've used, the fuses are programmed as part of 
the memory.  For example, on the COP8 devices, the code memory is from 
0x0000 to 0x7fff, while the fuses are from 0x8000 to 0x8005 (IIRC). 
Perhaps it's possible to pick a similar "standard" for the AVRs, so that 
gcc support for fuses needs nothing more than a new placed section in 
the linker files, along with a few macros in a C header file to fill the 
section, and support from avrdude and other programmers.  Obviously 
you'd also want to get Atmel's support in AVR Studio, but the benefits 
of having the fuse settings as part of the hex file would be large.

mvh.,
