Another question is my PIIX4 chip has device ID + vendor ID of
0x71108086. But it finally
was mapped to following ID of piix_pci_tbl[] array. Device of 0x7110
and 0x7010 should
be quit different, right?
    

Yes - I find tht one very odd - you might need to debug a bit to see what
is occuring if you think this is the case.

Alan/Jeff, I tried to install ATA driver on PIIX4. After fixing IRQ number
to 143 for primary and secondary channel. I got following output and
it seems the driver has been loaded sucessfully. However, I couldn't
see any information from /proc/devices. Do you have any ideas?

You need the SCSI disk driver - sd_mod.ko.
