i was able to probe the attached chip (SST39VF020) after adding the PCI ID, but reads returned all 0xFF. i need to verify that this is not correct, but i am quite certain that there is a working bootrom in there.
i forgot to mention a small detail in my first mail. i started by adding the pci id to nicintel_spi.c instead of nicintel.c because i thought: gigabit - probably spi flash. but that was wrong.
that was a happenstance though, because i now discovered that it needs a write enable just like the one in nicintel_spi_init.
after adding the pci ids to both, trying to probe with the spi code (which would loop forever) to write enable the nic...

Verifying flash... VERIFIED. Restoring MMIO space at 0xb77f300c
i then flashed another random image and flashrom tried to erase too (instead of skipping it like above). that also succeeded, yay.
of course for full, mergeable support we need to hook up the nic enable somehow... any suggestions?
