Hmm, by the way, if romsignature() needs this probe_kernel_address() thing, why doesn't romchecksum()?

I assume it's all in the same page, but CC'ing Zach is easier than
reading the code 8)

If we're talking hardware pages here; the romchecksum() might be done over an area upto 0xff x 512 = 130560 bytes (there's also an acces to the length byte at rom[2] in probe_roms(). I assume that one's okay if romsignature() ensured that the first page is in).
