Sorry for top posting. flashrom stopped working for me on intel DG33TL motherboard since I reported success. In the quoted older message below you can find what flashrom reported then, here is what it reports now:
Ah yes. You're hitting the problem that the "read" opcode is prohibited by the BIOS. Older flashrom versions ignored that and simply read the memory-mapped contents near the top of the address space. These dumps were incomplete, though, so in a way claiming to have dumped the ROM was a bug. The new code tries to get it right and hits the roadblock erected by the BIOS.
There's nothing we can do to fix it unless we discover a bug in the hardware (or implement the descriptor mode driver for ICH).
