This is a fix for a bug I see on my Toshiba laptop, where the ohci1394 
controller gets initialized improperly.  The patch adds two PCI fixups 
to arch/i386/pci/fixup.c, one that happens early on to cache the value 
of the PCI_CACHE_LINE_SIZE config register, and another that later 
restores the value, along with a valid IRQ number and some BAR values.  
I've tested it on my laptop, and it prevents me from running into what 
I consider to be a major bug: IRQ 11 is disabled by the IRQ debug code, 
causing my wireless to break.

Thanks to Rob for the original patch to ohci1394.c and Stefan for lots 
of proofreading and additional information collection.  I think the DMI 
system list is correct, but we may need to add some more PCI IDs to the 
PCI_FIXUP macros over time.

Thanks,
Jesse
