sis_66_set_dmamode() also handles early UDMA100 (SIS630 ET) but is
missing udma timing value for UDMA100. According to sis5513, this
should be 0x8000. This caused UDMA100 device to fail on pata_sis till
it downgrades to UDMA66 while it works fine on sis5513 at UDMA100.
Reported by Adam Blech.

I was just looking at this as we had a Red Hat bug for it 8)

I caught this one from a SUSE bug. I guess distros are useful from time
to time. :-)

Is this going into 2.6.23?
