A summary of my observations:

GCC 4.1.2 with m256x patch, switch/case: 
      warning during build, firmware unusable
GCC 4.1.2 with m256x patch, if/else: 
      no warning, firmware working partially
GCC 4.0.1 without patches, switch/case: 
      warning during build, firmware unusable
GCC 4.0.1 without patches, if/else: 
      no warning, firmware working partially
GCC 4.1.2 with m256x patch, switch/case + -mno-tablejump: 
      no warning, firmware works perfectly, as desired
GCC 3.4.6 with all patches from FreeBSD's avr-gcc-3 port, switch/case:
      no warning, firmware works perfectly, as desired 
      - and binary is ~300bytes smaller
