No need. The numbers made it clear: this is the same bug that hit the
hpt366 driver:
0000:00:10.0 RAID bus controller: Silicon Image, Inc. SiI 0649
Ultra ATA/100 PCI to ATA Host Controller (rev 01)
...

and the exact same cause too.
I wonder who the _hell_ has been sprinkling these _byte_ writes to the ROM
enable logic around?
I bet this will fix it..
