Actually, I tried to force it at 4MB starting at 0xff800000 since it 
made much sense looking at the e820 map. Or maybe I misunderstood 
something. It crashed with this:

<7>[ 9237.432181] esb2rom: esb2rom_init_one(): Unable to register 
resource 0xff800000-0xffbfffff - kernel bug?
<1>[ 9237.432262] Unable to handle kernel paging request at

I can dump here the disassembly of cfi_probe_chip if it's interesting...
