lol.. I've just been reading those since I have in my other hand a 82546EB 
based dual port PCI-X card with parallel rom on it. Of course the rom on that 
isn't supported either :)
It's another Atmel, this time a AT49BV002AN.. trivially adding it to flashchips.c 
isn't getting me anywhere, so I was just investigating the board enable stuff.

while I'll admit that's possible, have a look and tell me what you think

That very datasheet appears to be what was used to write the driver, the link 
to it is in the top of nicintel_spi.c and that's where I got the hope that 
it could maybe work :)

np, I'm happy to test stuff.
