You could do ugly things like this:

int i;
char *bios = __va(0xf0000);

for(i = 0; i < 0x10000 - 19; i++) {
if(memcmp(bios + i, "Soekris Engineering", 19) == 0) {
printk("soekris string found at 0x%x\n", i);
}
}

The string "net4801" is also in there (although I'm using a 4826).

If anyone knows a better way, I'd like to know it too.

Hmm, very ugly indeed! Where did you dig those offsets up from? Are they likely to work properly in non-Soekris devices? I think just relying on people not loading the module when not in the correct hardware is probably the best option at the moment...
