2.6.11-mm3: it87 sensor driver loads but doesn't attach as a client on amd64 gigabyte k8

Hi

I've been trying to get the it87 driver to work on my Gigabyte K8NF-9 
motherboard.  Found that if I hack out this bit with #if 0:

#if 0
#define REALLY_SLOW_IO
                         /* We need the timeouts for at least some 
IT87-like chips. But only
                            if we read 'undefined' registers. */
                         i = inb_p(address + 1);
                         if (inb_p(address + 2) != i
                          || inb_p(address + 3) != i
                          || inb_p(address + 7) != i) {
                                 err = -ENODEV;
                                 goto ERROR1;
                         }
#undef REALLY_SLOW_IO
#endif

then it loads and works perfectly.  With this in the driver loads but 
fails silently - the attach client fails.

Any ideas?  I'm not quite sure what the code is doing here.
